    1: # Example installation
    2: 
    3: ## Introduction
    4: 
    5: This chapter will guide you through the installation process. The concepts 
    6: presented here apply to all installation methods. The only difference is in the 
    7: way the distribution sets are fetched by the installer. Some details of the 
    8: installation differ depending on the NetBSD release: The examples from this 
    9: chapter were created with NetBSD 5.0.
   10: 
   11: ### Note
   12: 
   13: The following install screens are just examples. Do not simply copy them, as 
   14: your hardware and configuration details may be different!
   15: 
   16: ## The installation process
   17: 
   18: The installation process is divided logically in two parts. In the first part 
   19: you create a partition for NetBSD and write the disklabel for that partition. In 
   20: the second part you decide which distribution sets (subsets of the operating 
   21: system) you want to install and then extract the files into the newly created 
   22: partition(s).

   41: 
   42: XXX
   43: 
   44: The NetBSD install program sysinst allows you to change the keyboard layout 
   45: during the installation. If for some reason this does not work for you, you can 
   46: use the map in the following table.
   47: 
   48: ## Starting the installation
   49: 
   50: To start the installation of NetBSD, insert your chosen boot media (CD/DVD, USB 
   51: drive, floppy, etc.) and reboot the computer. The kernel on the installation 
   52: medium will be booted and start displaying a lot of messages on the screen about 
   53: hardware being detected.
   54: 
   55: ![Selecting the language](/guide/images/exinst_language.png)  
   56: **Selecting the language**
   57: 
   58: When the kernel has booted you will find yourself in the NetBSD installation 
   59: program, sysinst, shown in the previous figure. From here on you should follow 
   60: the instructions displayed on the screen, using the `INSTALL` document as a 
   61: companion reference. You will find the INSTALL document in various formats in 
   62: the root directory of the NetBSD release. The sysinst screens all have more or 
   63: less the same layout: the upper part of the screen shows a short description of 
   64: the current operation or a short help message, and the rest of the screen is 
   65: made up of interactive menus and prompts. To make a choice, use the cursor keys, 
   66: the `Ctrl+N` (next) and `Ctrl+P` (previous) keys, or press one of the letters 
   67: displayed left of each choice. Confirm your choice by pressing the Return key.
   68: 
   69: Start by selecting the language you prefer to use for the installation process.
   70: 
   71: The next screen will allow you to select a suitable keyboard type:
   72: 
   73: ![Selecting a keyboard type](/guide/images/exinst_keyboard.png)  
   74: **Selecting a keyboard type**
   75: 
   76: This will bring you to the main menu of the installation program:
   77: 
   78: ![The sysinst main menu](/guide/images/exinst_main.png)  
   79: **The sysinst main menu**
   80: 
   81: Choosing the *Install NetBSD to hard disk* option brings you to the next screen 
   82: , where you need to confirm that you want to continue the installation:
   83: 
   84: ![Confirming to install NetBSD](/guide/images/exinst_confirm.png)  
   85: **Confirming to install NetBSD**
   86: 
   87: After choosing *Yes* to continue, sysinst displays a list of one or more disks 
   88: and asks which one you want to install NetBSD on. In the example given in the 
   89: following figure, there are two disks, and NetBSD will be installed on `wd0`, 
   90: the first IDE disk found. If you use SCSI or external USB disks, the first will 
   91: be named `sd0`, the second `sd1` and so on.
   92: 
   93: ![Choosing a hard disk](/guide/images/exinst_select_disk.png)  
   94: **Choosing a hard disk**
   95: 
   96: The installer will then ask whether you want to do a full, minimal or custom 
   97: installation. NetBSD is broken into a collection of distributions sets. *Full 
   98: installation* is the default and will install all sets; *Minimal installation* 
   99: will only install a small core set, the minimum of what is needed for a working 
  100: system. If you select *Custom installation* you can select which sets you would 
  101: like to have installed. This step is shown here:
  102: 
  103: ![Full or custom installation](/guide/images/exinst_install-type.png)  
  104: **Full or custom installation**
  105: 
  106: If you choose to do a custom installation, sysinst will allow you to choose 
  107: which distribution sets to install, as shown in the following figure. At a 
  108: minimum, you must select a kernel and the *Base* and *System (/etc)* sets.
  109: 
  110: ![Selecting distribution sets](/guide/images/exinst_sets.png)  
  111: **Selecting distribution sets**
  112: 
  113: ## MBR partitions
  114: 
  115: The first important step of the installation has come: the partitioning of the 
  116: hard disk. First, you need to specify whether NetBSD will use a partition 
  117: (suggested choice) or the whole disk. In the former case it is still possible to 
  118: create a partition that uses the whole hard disk (see below) so we recommend 
  119: that you select this option as it keeps the BIOS partition table in a format 
  120: which is compatible with other operating systems.
  121: 
  122: ![Choosing the partitioning scheme](/guide/images/exinst_mbr.png)  
  123: **Choosing the partitioning scheme**
  124: 
  125: The next screen shows the current state of the MBR partition table on the hard 
  126: disk before the installation of NetBSD. There are four primary partitions, and 
  127: as you can see, this example disk is currently empty. If you do have other 
  128: partitions you can leave them around and install NetBSD on a partition that is 
  129: currently unused, or you can overwrite a partition to use it for NetBSD.
  130: 
  131: ![fdisk](/guide/images/exinst_fdisk.png)  
  132: **fdisk**
  133: 
  134: Deleting a partition is simple: after selecting the partition, a menu with 
  135: options for that partition will appear (see below). Change the partition kind to 
  136: *Delete partition* to remove the partition. Of course, if you want to use the 
  137: partition for NetBSD you can set the partition kind to *NetBSD*.
  138: 
  139: You can create a partition for NetBSD by selecting the partition you want to 
  140: install NetBSD to. The partition names `a` to `d` correspond to the four primary 
  141: partitions on other operating systems. After selecting a partition, a menu with 
  142: options for that partition will appear, as shown here:
  143: 
  144: ![Partition options](/guide/images/exinst_fdisk-type.png)  
  145: **Partition options**
  146: 
  147: To create a new partition, the following information must be supplied:
  148: 
  149:  * the type (kind) of the new partition
  150:  * the first (start) sector of the new partition
  151:  * the size of the new partition
  152: 
  153: Choose the partition type *NetBSD* for the new partition (using the `type` 
  154: option). The installation program will try to guess the *start* position based 
  155: on the end of the preceding partition. Change this value if necessary. The same 
  156: thing applies to the `size` option; the installation program will try to fill in 
  157: the space that is available until the next partition or the end of the disk 
  158: (depending on which comes first). You can change this value if it is incorrect, 
  159: or if you do not want NetBSD to use the suggested amount of space.
  160: 
  161: After you have chosen the partition type, start position, and size, it is a good 
  162: idea to set the name that should be used in the boot menu. You can do this by 
  163: selecting the *bootmenu* option and providing a label, e.g., `NetBSD`. It is a 
  164: good idea to repeat this step for other bootable partitions so you can boot both 
  165: NetBSD and a Windows system (or other operating systems) using the NetBSD 
  166: bootselector. If you are satisfied with the partition options, confirm your 
  167: choice by selecting *Partition OK*. Choose *Partition table OK* to leave the MBR 
  168: partition table editor.
  169: 
  170: If you have made an error in partitioning (for example you have created 
  171: overlapping partitions) sysinst will display a message and suggest that you go 
  172: back to the MBR partition editor (but you are also allowed to continue). If the 
  173: data is correct but the NetBSD partition lies outside the range of sectors which 
  174: is bootable by the BIOS, sysinst will warn you and ask if you want to proceed 
  175: anyway. Doing so may lead to problems on older PCs.
  176: 
  177: *Note*: This is not a limitation of NetBSD. Some old BIOSes cannot boot a 
  178: partition which lies outside the first 1024 cylinders. To fully understand the 
  179: problem you should study the different type of BIOSes and the many addressing 
  180: schemes that they use (*physical CHS*, *logical CHS*, *LBA*, ...). These topics 
  181: are not described in this guide.
  182: 
  183: On modern computers (those with support for *int13 extensions*), it is possible 
  184: to install NetBSD in partitions that live outside the first 8 GB of the hard 
  185: disk, provided that the NetBSD boot selector is installed.
  186: 
  187: Next, sysinst will offer to install a boot selector on the hard disk. This 
  188: screen is shown here:
  189: 
  190: ![Installing the boot selector](/guide/images/exinst_bootselect.png)  
  191: **Installing the boot selector**
  192: 
  193: At this point, the *BIOS partitions* (called *slices* on BSD systems) have been 
  194: created. They are also called *PC BIOS partitions*, *MBR partitions* or *fdisk 
  195: partitions*.
  196: 
  197: *Note*: Do not confuse the *slices* or *BIOS partitions* with the *BSD 
  198: partitions*, which are different things.
  199: 
  200: ## Disklabel partitions
  201: 
  202: Some platforms, like PC systems (amd64 and i386), use DOS-style MBR partitions 
  203: to separate file systems. The MBR partition you created earlier in the 
  204: installation process is necessary to make sure that other operating systems do 
  205: not overwrite the diskspace that you allocated to NetBSD.
  206: 
  207: NetBSD uses its own partition scheme, called a *disklabel*, which is stored at 
  208: the start of the MBR partition. In the next few steps you will create a 
  209: [disklabel(5)](http://netbsd.gw.com/cgi-bin/man-cgi?disklabel+5+NetBSD-5.0.1+i386) 
  210: and set the sizes of the NetBSD partitions, or use existing partition sizes, as 
  211: shown here:
  212: 
  213: ![Edit partitions?](/guide/images/exinst_disklabel.png)  
  214: **Edit partitions?**
  215: 
  216: When you choose to set the sizes of the NetBSD partitions you can define the 
  217: partitions you would like to create. The installation program will generate a 
  218: disklabel based on these settings. This installation screen is shown here:
  219: 
  220: ![Setting partition sizes](/guide/images/exinst_disklabel-change.png)  
  221: **Setting partition sizes**
  222: 
  223: The default partition scheme of just using a big `/` (root) file system (plus 
  224: swap) works fine with NetBSD, and there is little need to change this. The 
  225: previous figure shows how to change the size of the swap partition to 600 MB. 
  226: Changing `/tmp` to reside on a *RAM disk* 
  227: ([mfs(8)](http://netbsd.gw.com/cgi-bin/man-cgi?mfs+8+NetBSD-5.0.1+i386)) for 
  228: extra speed may be a good idea. Other partition schemes may use separate 
  229: partitions for `/var`, `/usr` and/or `/home`, but you should use your own 
  230: experience to decide if you need this.
  231: 
  232: The next step is to create the disklabel and edit its partitions, if necessary, 
  233: using the disklabel editor (see below). If you predefined the partition sizes in 
  234: the previous step, the resulting disklabel will probably fit your wishes. In 
  235: that case you can complete the process immediately by selecting *Partition sizes 
  236: ok*.
  237: 
  238: ![The disklabel editor](/guide/images/exinst_disklabel-partitions.png)  
  239: **The disklabel editor**
  240: 
  241: There are two reserved partitions, `c`, representing the NetBSD partition, and 
  242: `d`, representing the whole disk. You can edit all other partitions by using the 
  243: cursor keys and pressing the return key. You can add a partition by selecting an 
  244: unused slot and setting parameters for that partition. The partition editing 
  245: screen is shown below:
  246: 
  247: ![Disklabel partition editing](/guide/images/exinst_disklabel-partition-editor.png)  
  248: **Disklabel partition editing**
  249: 
  250: ## Setting the disk name
  251: 
  252: After defining the partitions in the new disklabel, the last item is to enter a 
  253: name for the NetBSD disk as shown bwlow. This can be used later to distinguish 
  254: between disklabels of otherwise identical disks.
  255: 
  256: ![Naming the NetBSD disk](/guide/images/exinst_diskname.png)  
  257: **Naming the NetBSD disk**
  258: 
  259: ## Last chance!
  260: 
  261: The installer now has all the data it needs to prepare the disk. Nothing has 
  262: been written to the disk at this point, and now is your last chance to abort the 
  263: installation process before actually writing data to the disk. Choose *no* to 
  264: abort the installation process and return to the main menu, or continue by 
  265: selecting *yes*.
  266: 
  267: ![Last chance to abort](/guide/images/exinst_last-chance.png)  
  268: **Last chance to abort**
  269: 
  270: ## The disk preparation process
  271: 
  272: After confirming that sysinst should prepare the disk, it will run 
  273: [disklabel(8)](http://netbsd.gw.com/cgi-bin/man-cgi?disklabel+8+NetBSD-5.0.1+i386) 
  274: to create the NetBSD partition layout and 
  275: [newfs(8)](http://netbsd.gw.com/cgi-bin/man-cgi?newfs+8+NetBSD-5.0.1+i386) to 
  276: create the file systems on the disk.
  277: 
  278: After preparing the NetBSD partitions and their filesystems, the next question 
  279: (shown in the next figure) is which *bootblocks* to install. Usually you will 
  280: choose the default of *BIOS console*, i.e., show boot messages on your 
  281: computer's display.
  282: 
  283: If you run a farm of machines without monitor, it may be more convenient to use 
  284: a serial console running on one of the serial ports. The menu also allows 
  285: changing the serial port's baud rate from the default of 9600 baud, 8 data bits, 
  286: no parity and one stopbit.
  287: 
  288: ![Selecting bootblocks](/guide/images/exinst_bootblocks.png)  
  289: **Selecting bootblocks**
  290: 
  291: ## Choosing the installation media
  292: 
  293: At this point, you have finished the first and most difficult part of the 
  294: installation!
  295: 
  296: The second half of the installation process consists of populating the file 
  297: systems by extracting the distribution sets that you selected earlier (base, 
  298: compiler tools, games, etc). Before unpacking the sets, sysinst asks what 
  299: information you would like to see during that process, as shown below. You can 
  300: choose between a progress bar, a display of the name of each extracted file, or 
  301: nothing.
  302: 
  303: ![Choosing the verbosity of the extraction process](/guide/images/exinst_verbosity.png)  
  304: **Choosing the verbosity of the extraction process**
  305: 
  306: Now sysinst needs to find the NetBSD sets and you must tell it where to find 
  307: them. The menu offers several choices, as shown below. The options are explained 
  308: in detail in the `INSTALL` documents.
  309: 
  310: ![Installation media](/guide/images/exinst_medium.png)  
  311: **Installation media**
  312: 
  313: ### Installing from CD-ROM or DVD
  314: 
  315: When selecting *CD-ROM / DVD*, sysinst asks the name of the CD-ROM or DVD device 
  316: and the directory in which the set files are stored, see below. The device is 
  317: usually `cd0` for the first CD-ROM or DVD drive, regardless of whether it is IDE 
  318: or SCSI (or even USB or FireWire).
  319: 
  320: ![CD-ROM/DVD installation](/guide/images/exinst_cdrom.png)  
  321: **CD-ROM/DVD installation**
  322: 
  323: ### The CD-ROM/DVD device name
  324: 
  325: If you don't know the name of the CD-ROM/DVD device, you can find by doing the 
  326: following:
  327: 
  328:  1. Press Ctrl-Z to pause sysinst and go to the shell prompt.
  329: 
  330:  2. Type the command:
  331: 
  332:         # dmesg
  333: 
  334:     This will show the kernel startup messages, including the name of the CD-ROM device, for example *cd0*.
  335: 
  336:  3. If the display scrolls too quickly, you can also use **more**:
  337: 
  338:         # dmesg | more
  339: 
  340:  4. Go back to the installation program with the command:
  341: 
  342:         # fg
  343: 
  344: ### Installing from an unmounted file system
  345: 
  346: The next figure shows the menu to install NetBSD from an unmounted file system. 
  347: It is necessary to specify the device (*Device*), the file system of the device 
  348: (*File system*) and the path to the install sets (*Set directory*). The setting 
  349: for the *Base directory* is optional and can be kept blank.
  350: 
  351: In the following example the install sets are stored on a *MSDOS* file system, 
  352: on partition `e` on the device `sd0`.
  353: 
  354: ![Mounting a file system](/guide/images/exinst_mount.png)  
  355: **Mounting a file system**
  356: 
  357: It is usually necessary to specify the device name and the partition. The 
  358: following figure shows how to specify device `sd0` with partition `e`.
  359: 
  360: ![Mounting a partition](/guide/images/exinst_mount-partition.png)  
  361: **Mounting a partition**
  362: 
  363: In the next figure, the file system type is specified. It is `msdos` but it 
  364: could also be the NetBSD file system `ffs` or `ext2fs`, a Linux file system. The 
  365: *Base directory item is left blank and the binary sets are stored under `/sets`. 
  366: Choosing *Continue* will start the extraction of the sets.
  367: *
  368: 
  369: ![Accessing a MSDOS file system](/guide/images/exinst_mount-msdos.png)  
  370: **Accessing a MSDOS file system**
  371: 
  372: ### Installing via FTP
  373: 
  374: If you choose to install from a local network or the Internet via FTP, sysinst 
  375: will configure the system's network connection, download the selected set files 
  376: to a temporary directory, and then extract them.
  377: 
  378: NetBSD currently supports installation via ethernet, USB ethernet or wireless, 
  379: and wireless LAN. Installation via DSL (PPP over Ethernet) is not supported 
  380: during installation.
  381: 
  382: The first step shown in the next figure further below consists of selecting 
  383: which network card to configure. sysinst will determine a list of available 
  384: network interfaces, present them and ask which one to use.
  385: 
  386: *Note*: The exact names of your network interfaces depend on the hardware you 
  387: use. Example interfaces are `wm` for Intel Gigabit interfaces, `ne` for NE2000 
  388: and compatible ethernet cards, and `ath` for Atheros based wireless cards. This 
  389: list is by no means complete, and NetBSD supports many more network devices.
  390: 
  391: To get a list of network interfaces available on your system, interrupt the 
  392: installation process by pressing `Ctrl+Z`, then enter
  393: 
  394:     # ifconfig -a
  395:     ne2: flags=8822<UP,BROADCAST,NOTRAILERS,SIMPLEX,MULTICAST> mtu 1500
  396:             address: 00:06:0d:c6:73:d5
  397:             media: Ethernet autoselect 10baseT full-duplex
  398:             status: active
  399:             inet 0.0.0.0 netmask 0xffffff00 broadcast 0.0.0.0

  409:     strip0: flags=0 mtu 1100
  410:     strip1: flags=0 mtu 1100 
  411: 
  412: To get more information about all the devices found during system startup, 
  413: including network devices, type
  414: 
  415:     # dmesg | more
  416: 
  417: You can return to the NetBSD installation by typing
  418: 
  419:     # fg
  420: 
  421: ![Which network interface to configure](/guide/images/exinst_ftp-if.png)  
  422: **Which network interface to configure**
  423: 
  424: Next, you have a chance to set your network medium.
  425: 
  426: *Note*: It is unlikely that you will need to enter anything other than the 
  427: default here. If you experience problems like very slow transfers or timeouts, 
  428: you may, for example, force different duplex settings for ethernet cards. To get 
  429: a list of supported media and media options for a given network device (ne2, for 
  430: example), escape from sysinst by pressing `Ctrl+Z`, then enter:
  431: 
  432:     # ifconfig -m ne2
  433:     ne2: flags=8822<UP,BROADCAST,NOTRAILERS,SIMPLEX,MULTICAST> mtu 1500
  434:             address: 00:03:0d:c6:73:d5
  435:             media: Ethernet 10baseT full-duplex
  436:             status: active
  437:             supported Ethernet media:
  438:                     media 10baseT
  439:                     media 10baseT mediaopt full-duplex
  440:                     media 10base2
  441:                     media autoselect
  442: 
  443: The various values printed after `media` may be of interest here, including 
  444: keywords like `autoselect` but also including any `mediaopt` settings.
  445: 
  446: Return to the installation by typing:
  447: 
  448:     # fg
  449: 
  450: The next question will be whether you want to perform DHCP autoconfiguration as 
  451: shown in the figure below. Answer *Yes* if you have a DHCP *Dynamic Host 
  452: Configuration Protocol* (DHCP) running somewhere on your network, and sysinst 
  453: will fetch a number of defaults from it. Answer *No* to enter all the values 
  454: manually.
  455: 
  456: We will assume you answered *No* and go into all the questions asked in detail.
  457: 
  458: ![Using DHCP for network configuration](/guide/images/exinst_ftp-dhcp.png)  
  459: **Using DHCP for network configuration**
  460: 
  461: The image below shows the questions asked for the network configuration. The 
  462: values to be entered are:
  463: 
  464:  * *Your DNS Domain:* -- This is the name of the domain you are in.
  465:  * *Your hostname:* -- The name by which other machines can usually address your 
  466:    computer. Not used during installation.
  467:  * *Your IPv4 number:* -- Enter your numerical Internet Protocol address in 
  468:    *dotted quad* notation here, for example, 192.168.1.3
  469:  * *IPv4 Netmask:* -- The netmask for your network, either given as a hex value 
  470:    (`0xffffff00`) or in dotted-quad notation (`255.255.255.0`).
  471:  * *IPv4 gateway:* -- Your router's (or default gateway's) IP address. Do not 
  472:    use a hostname here!
  473:  * *IPv4 name server:* -- Your (first) DNS server's IP address. Again, don't use 
  474:    a hostname.
  475: 
  476: ![Entering and configuring network data](/guide/images/exinst_ftp-cfg.png)  
  477: **Entering and configuring network data**
  478: 
  479: After answering all of your network configuration info, it will be displayed, 
  480: and you will have a chance to go back and make changes.
  481: 
  482: ![Confirming network parameters](/guide/images/exinst_ftp-cfgok.png)  
  483: **Confirming network parameters**
  484: 
  485: sysinst will now run a few commands (not displayed in detail here) to configure 
  486: the network: flushing the routing table, setting the default route, and testing 
  487: if the network connection is operational.
  488: 
  489: Now that you have a functional network connection, you must tell the installer 
  490: how to get the distribution sets, as shown in the next figure.
  491: 
  492: When you are satisfied with your settings (the defaults work most of the time), 
  493: choose *Get Distribution* to continue.
  494: 
  495: ![Defining the FTP settings](/guide/images/exinst_ftp-src.png)  
  496: **Defining the FTP settings**
  497: 
  498: ### Installing via NFS
  499: 
  500: If you want to install NetBSD from a server in your local network, NFS is an 
  501: alternative to FTP.
  502: 
  503: *Note*: Using this installation method requires the ability to set up an NFS 
  504: server, a topic which is not discussed here.
  505: 
  506: As shown below, you must specify the IP address of the NFS server with "Host", 
  507: the "Base directory" that is *exported* by the NFS server, and the "Set 
  508: directory", which contains the install sets.
  509: 
  510: ![NFS install screen](/guide/images/exinst_nfs.png)  
  511: **NFS install screen**
  512: 
  513: The following image shows an example: Host `192.168.1.50` is the NFS server that 
  514: provides the directory `/home/username/Downloads` The NetBSD install sets are 
  515: stored in the directory `/home/username/Downloads/sets` on the NFS server. 
  516: Choose *Continue* to start the installation of the distribution sets.
  517: 
  518: ![NFS example](/guide/images/exinst_nfs-example.png)  
  519: **NFS example**
  520: 
  521: ## Extracting sets
  522: 
  523: After the method for obtaining distribution sets has been chosen, and (if 
  524: applicable) after those sets have been transferred, they will be extracted into 
  525: the new NetBSD file system.
  526: 
  527: After extracting all selected sets, sysinst will create device nodes in the 
  528: `/dev` directory and then display a message saying that everything went well.
  529: 
  530: Another message will let you know that the set extraction is now completed, and 
  531: that you will have an opportunity to configure some essential things before 
  532: finishing the NetBSD installation:
  533: 
  534: ![Extraction of sets completed](/guide/images/exinst_extraction-complete.png)  
  535: **Extraction of sets completed**
  536: 
  537: ## System configuration
  538: 
  539: The first thing you can configure is your timezone. It is *Universal Time 
  540: Coordinated* (UTC) by default, and you can use the two-level menu of 
  541: continents/countries and cities shown below to select your timezone with the 
  542: Return key. Next, press `x` followed by Return to exit timezone selection.
  543: 
  544: ![Selecting the system's time zone](/guide/images/exinst_timezone.png)  
  545: **Selecting the system's time zone**
  546: 
  547: At this point, you are given the option to choose a password encryption scheme. 
  548: While *DES* is the standard algorithm used on most Unix systems, *MD5*, 
  549: *Blowfish*, and *SHA1* allow longer passwords than DES, which only uses the 
  550: first eight characters of the password that is entered. DES is still useful for 
  551: interoperability with other operating systems.
  552: 
  553: ![Selecting a password encryption scheme](/guide/images/exinst_cipher.png)  
  554: **Selecting a password encryption scheme**
  555: 
  556: After choosing the password cipher you are asked if you want to set the root 
  557: password. It is recommended to set a root password at this point for security 
  558: reasons.
  559: 
  560: ![Set a root password?](/guide/images/exinst_passwd.png)  
  561: **Set a root password?**
  562: 
  563: When you agree to set a root password, sysinst will run the 
  564: [passwd(1)](http://netbsd.gw.com/cgi-bin/man-cgi?passwd+1+NetBSD-5.0.1+i386) 
  565: utility for you. Please note that the password is not echoed.
  566: 
  567: ![Setting root password](/guide/images/exinst_passwd2.png)  
  568: **Setting root password**
  569: 
  570: The next menu allows you to choose which command line interpreter - also known 
  571: as a `shell` - will be used for the root account. The default is the classic 
  572: *Bourne shell*, 
  573: [sh(1)](http://netbsd.gw.com/cgi-bin/man-cgi?sh+1+NetBSD-5.0.1+i386). Other 
  574: choices are the *Korn shell* 
  575: ([ksh(1)](http://netbsd.gw.com/cgi-bin/man-cgi?ksh+1+NetBSD-5.0.1+i386)) and the 
  576: *C shell* 
  577: ([csh(1)](http://netbsd.gw.com/cgi-bin/man-cgi?csh+1+NetBSD-5.0.1+i386)). If, 
  578: upon reading this, you don't have some idea of which shell you prefer, simply 
  579: use the default, as this is a highly subjective decision. Should you later 
  580: change your mind, root's shell can always be changed.
  581: 
  582: ![Choosing a shell](/guide/images/exinst_shell.png)  
  583: **Choosing a shell**
  584: 
  585: ## Finishing the installation
  586: 
  587: At this point the installation is finished.
  588: 
  589: ![Installation completed](/guide/images/exinst_completed.png)  
  590: **Installation completed**
  591: 
  592: After passing the dialog that confirms the installation, sysinst will return to 
  593: the main menu. Remove any installation media (CD, floppy, etc.) and choose 
  594: *Reboot the computer* to boot your new NetBSD installation.
  595:
