                     18: The goal of this project is to enhance the NetBSD system installer (sysinst) to provide additional support for (in order):
                     19: 
1.4       wiki       20: * partition disks using GPT
                     21: * prepare multiple disks
                     22: * combine multiple partitions to raid/lvm volumes
                     23: * encrypt partitions via cgd
1.1       jmmv       24: * other enhancements
                     25: 
1.3       wiki       26: The installer currently supports installing the system to any available single disk. It is possible to select which parts (distribution sets) of the system to install, and also to customise the disk partition layout. Sysinst can also use vnode pseudo disks, so can be tested without the need to re-install the host system.
1.1       jmmv       27: 
1.5     ! wiki       28: The first goal is to allow partitioning disks using the GUID partition table (GPT). The current partitioning code is tied heavily to the BSD disklabel. Fixing it is straight forward, but both methods have to be offered and only some architectures can boot from GPT disks.
1.1       jmmv       29: 
1.4       wiki       30: The second goal is to allow preparing several disks. This part would also be usefull (see "other enhancements" below) as a stand-alone tool. Various disks may be partitioned using different shemes, for example when the boot disk can not use GPT, but secondary (large) disks should use it. This part also is a direct prerequisite for the following one.
1.1       jmmv       31: 
1.4       wiki       32: The third goal is to (optionally) create logical volumes from multiple partitions or disks, either using raidframe or LVM. This includes making the volumes bootable, if possible.
1.1       jmmv       33: 
1.3       wiki       34: The fourth goal is to add support for creating and installing on to cgd (encrypted) partitions. The initial support will not be for the boot partition, but other partitions should be supported.
                     35: 
1.1       jmmv       36: The other enhancements that might be possible are (not in priority order):
                     37: 
                     38: #### user interface
                     39: * customise colours
                     40: * add "back" and "forward" menu options
                     41: * run parts of the installer independently (e.g. disk partitioning, set installation)
                     42: 
                     43: #### cgd enhancements
                     44: * add the ability to encrypt the whole disk and to enter the decryption key at boot time
                     45: 
                     46: #### automated test setup
                     47: * add the ability to install Anita for automated testing 
                     48: 
                     49: The candidate must have:
                     50: 
                     51: * familiarity with the system installer. You should have used sysinst to install the system.
                     52: * familiarity with C programming. The system installer program consists of C code.
                     53: * a test system, preferably with a 2nd bootable device.
                     54: 
                     55: The following would also be useful:
                     56: 
                     57: * familiarity with NetBSD.
                     58: * familiarity with user interface programming using curses.
