Annotation of wikisrc/users/mlelstv/device-naming.mdwn, revision 1.1

1.1     ! mlelstv     1: * Rationale
        !             2: 
        !             3: - Talk about device names used in /etc/fstab
        !             4: - autoconf: device are named driver+unit, unit is just the next unused unit number
        !             5: - static hardware has well-defined device names
        !             6: - not-so static hardware often has distinction between different controllers and thus maybe different drivers
        !             7: - partitions on device names are just private count (a,b,c,...) per device
        !             8: - wedges are partitions that look like units for a single same driver
        !             9:   - no distinction by controller / driver
        !            10:   - no distinction by private counter
        !            11: 
        !            12: * Wedge names
        !            13: 
        !            14: - Wedges are a unified interface to partitions
        !            15: - One wedge carries one filesystem
        !            16: - Can have a name that defaults to a UUID
        !            17: - Names can be looked up in userland
        !            18: - util function getfsspecname()
        !            19: - Patches for userland tools (mount,umount,swapctl,fsck,quotaon,quotacheck,edquota,dumpfs,tunefs,dump)
        !            20: - Kernel interface still uses driver+unit.
        !            21: - No reverse mapping, e.g. for df
