# pecuniary loss) arising out of the use of or inability to use this script.

# NOTES:
# 1. This script requires that you have a working floppy drive, with an
#     appropriate /etc/fstab entry.  My /etc/fstab has this:
#      /dev/fd0       /mnt/floppy      auto    noauto,owner    0 0
#     I have a symlink to /a -> /mnt/floppy
#     This lets people who expect to find stuff in /mnt be OK, but is easier
#     for me to type.
# 2. OBSOLETE: Every time you update the kernel, you have to update the mkbootdisk
#     line too.  `ls /boot/vmlinuz-* | cut -d - -f 2-` does this now.
# 3. I only grab fdisk -l info from /dev/hda, if you have more hard
#     drives, add them too.
# 4. You can do everything but the floppy stuff by "$0 nofpy"
# 5. Since this may not always run "su -" I have included paths.  You'll
#     have to adjust them if your system is different.
# 6. mkkickstart is being deprecated in favor of ksconfig.  The problem is
#     that ksconfig is graphical only :-(!  I'm investigating...
# 7. You might want to think about installing and running RedHat's sysreport
#     too.  That had lots of good (debugging) info, but is a bit overkill
#     for the scope of this script...
