# I wouldn't be so bold as to say this is perfect, but I think it does a
# rather nice job creating devices. Parts that could be improved is
# support for other than the auto-detecting floppy devices, but I can't
# think of a clean way to name the devices. There should be support
# for more pty groups, and also for SCSI tapes. The SCSI device names
# are also somewhat off from what Drew Eckhardt suggested, but they
# follow the same format as the hd* names.
#

#
# I've added all the 'hard' floppy devices - the names are /dev/fd#D#, where
# the first number is the drive number (0 or 1), the D designates the density of
# the drive, and size (d = 5.25" 360K, h = 5.25" 1200k, D = 3.5" 720k, H = 3.5"
# 1440k), and the final number represents the disk size, in kilobytes - this can
# be 360, 720, 1200, or 1400.
#
#
# Because SCSI devices should now support extended partitions, sd[ab][5-8] are
# created in addition to those generated before - this matches up with hd*. It
# is possible to have (and create) higher numbered partitions, but it is
# generally not done, so it is not done by default.
#
#
# I've added par[0-3], which correspond to lp[0-3]. The par names are defined
# by the latest Linux Standards draft, but the lp names are in common usage.
#
# ttys[1-4] were shifted down to ttys[0-3], as they should have been
# originally.
#
# added bus mouse device (major 10, minor 0)
#
# Fixed some of the owners and permissions.
