07/27
- if the user is foolish enough to use /dev/md0 as boot device,
  call lilo -M /dev/hda to make sure lilo does its job properly
- better NFS+nuke support

07/20
- use backup's i-want-my-lvm file
- be sure to use archives' raidtab when restoring

07/18
- use /tmp/isodir for NFS if DR mode
- better support of users who boot from LVM CD and nuke-restore non-LVM backups

07/12
- bugfix to allow user to burn ISOs to CDs and restore from CDs (not original src)

06/29
- mount ext3 partitions as ext2, just in case :)

06/26
- delete make_relevant_partition_bootable()

06/19
- futzed with the call to mount floppy, to stop it from locking up on my AMD64 system

06/14
- shell out to /mnt/RESTORING chroot in order to let user install GRUB
  manually if automatic GRUB installation fails

06/15
- Added check for different 'isodir' chosen by user than stored in the archive
  Conor Daly <conor.daly@met.ie>

04/17
- replaced INTERNAL_TAPE_BLK_SIZE with bkpinfo->internal_tape_block_size

04/09
- don't try to mount CD if tape bkp

04/03
- trying to copy tmp/mondo-restore.cfg to itself - silly! - fixed

04/02
- when extracting cfg file and mountlist from all.tar.gz (tape copy),
  use block size of INTERNAL_TAPE_BLK_SIZE, not TAPE_BLOCK_SIZE

02/21
- don't use 'mv -v' cos Busybox won't support it

02/09
- make hole for cfg file before moving it (line 2094 or so)

02/03
- changed a couple of refs to filelist.full, to filelist.full.gz

01/16/2004
- instead of copying filelist, use 'ln -sf' to link to original;
  saves space

11/20/2003
- also retrieve /tmp/mountlist.txt if user wants

11/16
- fixed NFS path bug affecting the extractions of filelist/biggielist
  during selective restore

11/02
- fixed mount_cdrom() to run properly w/ nfs restores
- mount_device() returns 0 if swap mount fails cos swap isn't crucial

10/17
- run_grub() uses MNT_RESTORING instead of "/mnt/RESTORING"

10/26
- cleaned up run_grub()

10/25
- fixed mount_cdrom() to run properly w/ nfs restores

10/21
- mount_device() returns 0 if swap mount fails cos swap isn't crucial

10/15
- run_grub() now uses its initiative instead
  of calling grub-install

10/10
- don't leave copies of filelist.full lying around, clogging up
  the ramdisk, there's a good fellow :-)

10/02
- added 'dvd' to the range of media types I'll understand
- fixed iso->cdr problem (thanks, Stan Benoit & Fred Beondo)

09/24
- try lots of tape devs if /dev/st0 fails

09/23/2003
- first incarnation
