# - fix for 'skip the tape datadisks' bug (Joseph Smith)
#
# 10/13/2004
# - echo 0 > /proc/sys/kernel/exec-shield to disable exec-shield
#
# 07/25
# - removed sbminst
#
# 06/25
# - klogd -c 2 (was -c 5)
#
# 06/21
# - experimented w/ calling ctrlaltdel to setup soft reset
# - don't softlink /var/log
#
# 06/16
# - insmod dm_mod as well as dm-mod
#
# 05/24
# - added Andree's vc.tgz
#
# 05/14
# - open => openvt (part of busybox)
# - nash removed. dm.tgz added
#
# 04/21
# - compare original lsmod output w/ new lsmod output
#
# 04/13
# - mount /sys if appropriate
#
# 04/03
# - use 'dd if=$tapedev bs=32k count=1024' instead of 'tar -zxf $tapedev'
#   to extract aux datadisk files from tape
#
# 25/03
# - wait 7s, not 2s, while installing modules
#
# 18/01/2004
# - logging mondo-restore.cfg, not mondo-restore.log --- FIXED
#
# 11/23/2003
# - if find-and-mount-cdrom fails once, try again
# - open scrolling log of /tmp/mondo-restore.log later than previously
#
# 11/18
# - disabled clear()'s
# - reboot at end
#
# 11/15
# - softlink /var/log to /tmp/tmpfs/var/log
# - klogd -c 5 now (was -c 1)
#
# 11/10
# - don't call mondorestore if backup-media-type is not specified in
#   config file /tmp/mondo-restore.cfg
#
# 10/21
# - softlink nano to pico if nano found
#
# 10/16
# - create /dev/md/* softlinks if necessary
#
# 10/12
# - start devfs if /tmp/USE-DEVFS found
# - create simple /etc/devfsd.conf file
#
# 10/09
# - try various mount commands to get tmpfs online (use initiative)
#
# 09/24
# - also try /dev/st0, /dev/osst0, /dev/ht0 if [tapedev] fails
# - modify media-dev in mondo-restore.cfg if we succeed :)
#
# 09/15
# - create /tmp/null and /tmp/stdout and /tmp/stderr
#   as copies of the real thing, just in case partimagehack
#   still uses them
# 
# 08/01
# - tmpfs ramdisk is now 48m
#
# 07/14
# - added mkdirs at start
#
# 06/04
# - remount root as rw just in case
#
# 05/04
# - replaced /mnt/groovy-stuff with $GROOVY
#
# 04/30
# - if your CD was created by Mondoarchive when it backed up
#   to ISO(s) then re-jig tmp/mondo-restore.cfg accordingly;
#   this is nec. if you backup to a hard disk directory but
#   then burn the ISOs to physical CDs
#
# 04/26
# - offer user the chance to specify another tape device, if
#   the one they specified at backup-time refuses to act as 
#   aux data disk at boot-time
#
# 04/21
# - start scsi if cciss
# - use ataraid.tgz too
#
# 05/03
# - mount / -o rw,remount at end, just in case
#   RH9 futzes with the mountpoint
#
# 04/04
# - increased tmpfs ramdisk size from 34m to 38m
#
# 01/01 - 01/31/2003
# - fixed issue with LVM and SW Raid devices (Brian Borgeson)
# - friendlier 'upgrade your ram' msg
# - better fallback msg
# - if /tmp/2880.siz exists then assume boot CD
#
# 11/01 - 12/31/2002
# - updated intro msg
# - if /dev/boot_device and /BOOTLOADER.DEVICE exist then
#   copy device /dev/boot_device to pathname contained
#   in /BOOTLOADER.DEVICE text file
#
# 04/01 - 08/31/2002
# - handle new 'backup_media_type' entry in mondo-restore.cfg
# - added 'sleep 2' at start of WelcomeMessage
# - disabled a silly 'abort' line at end
# - better handling of devfs (DuckX) --- new RunDevfsd()
# - assume start-nfs is in /sbin
# - extract rd.tgz, raw.tgz, ida.tgz, cciss.tgz to /; they include
#   /dev entries which would otherwise fill up the ramdisk at bkp-time
#
# 01/01 - 03/31/2002
# - Carl Wilhelm Soderstrom disabled exec sh; replaced with exit 1
# - if you are an idiot & your computer has very little RAM,
#   this script will no longer abort; it will merely warn you
# - run chmod 755 `which start-nfs` before running start-nfs
# - use a ramdisk for /tmp (after copying old /tmp stuff into it)
# - fixed segfaults ('open') by replacing 'sh' call with '/bin/sh' call
# - changed LaunchTerminals() to try to work with newly-compiled 'open'
# - don't write 'start-nfs error' if start-nfs doesn't exist; just go on
# - added tmpfs and some space-checking
# - cleaned up script
# - added stuff to start NFS services if necessary
# - reordered some of the main() stuff, for elegance's sake
# - added Petris and 'tail -f /tmp/mondo-restore.log' to LaunchTerminals()
# - changed /usr/share/ to /usr/local/
#
# 2001
# - fix some typos
# - added lots of cool stuff to make Mindi _nearly_ boot from tape
# - restructured the welcome msg echoed to screen
# - broke up spaghetti code; made lots of subroutines
