07/20
- when starting RAID, don't do it twice :)
- moved Joshua's new get_phys_size_of_drive() code
  from resize_drive... into get_phys_size_of_drive()

06/29
- make sure software RAID devices are formatted IF user says they're to be
- drivelist is struct now, not char[][]

06/26
- drop make_relevant_partition_bootable(); do it yourself in C (mostly)
- offer to reboot if partition table is locked up by the kernel

06/22
- be sure not to resize non-NTFS images when restoring
- set non-NTFS images' partition types properly

06/19
- shut down all LVMs and VGs before prepping

05/07
- usage of parted2fdisk instead of fdisk alone (ia32/ia64 compatibility)
  BCO

03/31
- rewrote partitioning and formatting code to call fdisk once per disk

10/21/2003
- suspend/resume Newt gui before/after calling do_my_funky_lvm_stuff()

10/20
- rewrote format_everything() - what a mess it was.
  It now does things in three phases:-
  - formats software RAID devices (/dev/md0, etc.)
  - formats and configures LVM devices
  - formats regular partitions (/dev/hda1, /dev/sdb2, etc.) 
    and any LVMs recently prepped

10/07
- use strstr(format, "raid") instead of strcmp(format,"raid") to determin
  if partition is a RAID component

09/23
- better comments

09/18
- better logging of RAID activity

05/05
- added Joshua Oreman's FreeBSD patches

04/30
- added textonly mode

04/24
- added lots of assert()'s and log_OS_error()'s

04/21
- format_everything() --- don't let bar go too far
- mkfs -c to check for bad blocks when formatting

04/04
- misc clean-up (Tom Mortell)

01/15/2003
- added code for LVM and SW Raid (Brian Borgeson)

12/10/2002
- line 1238: friendlier output

11/20
- when wiping a given device in preparation for partitioning + formatting
  it, don't wipe the MBR; just the partition table. That allows for
  stupid-ass Compaq users who like to play with their MBR's.
- disable mountlist.txt-->mountlist.txt.pre-resize copying (superfluous)

09/09
- run_program_and_log_output() now takes boolean operator to specify
  whether it will log its activities in the event of _success_

07/01 - 07/31
- added hooks to libmondo
- RAID enhancements (Philippe de Muyter)

01/01 - 03/31
- partition_device() will refuse to partition /dev/mdX now (cos it's a
  virtual drive); however, it will return 0 (i.e. not an error)
- make_list_of_drives() will exclude /dev/md* from list
- mkreiserfs -ff instead of -q (Andy Glass)
- don't resize drive if drive not found (or if its size cannot be det'd)
- when generating list of drives from mountlist, skip the 'p' at the end
  of drive name if /dev/ida/ or /dev/cciss/; just do it (Michael Eisenberg)
- don't specify journal size when formatting ext3
  (used to have -Jsize=10 in the call to mkfs)
- handles files >2GB in size
- format interactively, if Interactive Mode
- removed reference to g_tape_size
- when executing /tmp/i-want-my-lvm, only record the error# if the command
  was _not_ an 'insmod' command
- pass partition size to fdisk in Kilobytes now, not Megabytes
- log fdisk's output to /tmp/mondo-restore.log if it fails
- don't try to format partitions of type 'image'
- don't type to set types of 'image' partitions
- if format code is 1 or 2 chars then assume it is a hex string
- took out all '/ /' comments
- don't extrapolate/add partition from RAID dev to mountlist if it's already
  present in mountlist
- less repetitive logging in the event of vacuum-packing of last part'n
- no extrapolation at all: RAID partitions should be listed in mountlist
  already, thanks to either Mindi v0.5x or the mountlist editor itself
- no longer say, 'and logging to...' when setting a partition's type
- don't run mkfs on RAID partitions (/dev/hd*, /dev/sd*); just set type
- the setting of a partition's type now takes place in a separate subroutine
  from the subroutine that actually creates the partition
- no need to set type if 83: 83 is the default (under fdisk)
- turned on '-Wall'; cleaned up some cruft
- if vacuum-packing partition (i.e. size=0MB --> max) then say, "(maximum)"
  not, "(0 MB)"

11/22/2001
- preliminary code review
- created on Nov 22nd, 2001
