.


01/07/2005
- sensibly_set_tmpdir_and_scratchdir() --- exclude smb and smbfs and (new) cifs

10/23
- if root mounted at '/dev/rd/' then say FALSE, not mounted on ramdisk
  just to please Fred Beondo :-p

07/25
- updated get_phys_size_of_drive() to support newer, larger drives

07/18
- better support of users who boot from LVM CD and nuke-restore non-LVM backups

07/08
- BLKGETSIZE64 instead of BLKGETIO..whatever (Joshua)
- amended to use BLKGETSIZE if BLKGETSIZE64 missing (Hugo)
- resort to HDIO_GETGEO if BLKGETSIZE and BLKGETSIZE63 fail


06/25
- added Mandrake 9.2 support to which_boot_loader()
- cleaned up find_cdrom_device()

06/23
- rewrote resolve_softlinks_to_get_to_actual_device_file() in C

06/17
- don't use star automatically if SELINUX detected; let user do that

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

04/17
- replaced INTERNAL_TAPE_BLK_SIZE with bkpinfo->internal_tape_block_size

04/13
- if kernel >= 2.6 then ask for /dev entry, not SCSI node

04/12
- in mount_CDROM_...whatever, don't use bkpinfo_DONTUSETHIS to see if
  mounting a real CD device; look for /dev/ at start of $device instead

04/04
- when testing for tape drive, use INTERNAL_TAPE_BLK_SIZE, not TAPE_BLOCK_SIZE

04/03
- don't eject/retract drive if ISO

02/23/2004
- changed strstr() to strncmp() in a few places

12/11/2003
- if we can't find the DVD using dvdrecord then try it w/cdrecord

11/15
- changed a few []s to char*s
- better support of multiple CD-ROM drives

11/14
- better find_cdrom_device(), to cope w/ multiple CD writers

10/26
- call 'mt -f %s offline' to eject tape drive in eject_device()

10/25
- ask user to confirm which NFS share to mount
- improved which_boot_loader()

10/22
- tweaked find_cdrom_device() and find_cdrw_device()
- created find_dvd_device()

10/21
- changed "/mnt/cdrom" to MNT_CDROM

09/28
- interactive gui no longer asks dvd's speed

09/26
- interactive gui now supports dvd

09/23
- malloc/free global strings in new subroutines - malloc_libmondo_global_strings()
  and free_libmondo_global_strings() - which are in libmondo-tools.c

09/21
- ask for CD size when backing up interactively
- offer to exclude NFS shares if they're present

09/20
- exclude /dev/shm from sensibly_*()

09/18
- less verbose logging when insisting on CD #n

09/09
- added resolve_softlinks_to_get_to_actual_device_file()

09/05
- rewrote inisist_on_this_cd_number() and what_number_cd_is_this()

09/02
- is_this_a_valid_disk_format() -- treat ntfs (a.k.a. type 7) as recognized format
  just in case user's backup includes a partimagehack-imaged drive

08/01 - 08/31
- better boot-time tape detection
- remove backup-time, erroneous, "remove floppy" msg
- working on am_I_in_disaster_recovery_mode()
- interactively_obtain_...() - pause & ask user to remove CD/floppy

06/01 - 07/31
- in which_boot_loader(), also search /dev/cciss for boot loader
- fixed calls to popup_and_get_string()
- fixed bug in get_phys_size_of_drive()
- fixed bug in where_is_root_mounted()
- commented out a spurious assert()

05/01 - 05/31
- superior get_phys_size_of_drive() (Joshua Oreman)
- fixed call to inject_device() --- Andree L.
- find_cdrom_device() now may, if asked to, mount drive if possible,
  to test that it has a CD in it; it then unmounts
- mount_CDROM_here() now calls retract_cd_and_defeat_autorun() as well
- fixed support for subdir-within-NFS-mount
- cleaned up some FreeBSD-specific stuff
- added Joshua Oreman's FreeBSD patches
- mount_CDROM_here() --- mkdir -p mountpt
- add older drive support to get_phys_size_of_drive()

04/01 - 04/30
- made which_boot_loader() more friendly towards Red Hat 9
- find_and_mount_actual_cd() retracts all CD trays
- added lots of log_OS_error()'s and assert()'s
- fix ISO support in interactively_restore_...()
- made find_cdrom_device() skip dmesg if second-stage string is empty
- in find_cdrw_device(), find cdrecord before dvdrecord
- fixed am_i_in_disaster_recovery_mode()
- fixed insist_on_this_cd_number()

03/01 - 03/31
- more work on find_cdrom_device()
- find_cdrom_device() --- if nonexistent/not found then
  make sure to return '' as dev str and 1 as res
- cleaner find_cdrom_device(), to find DVD instead of CD-ROM
  as last resort
- fix insist_on_this_cd_number()
- add user the speed of CD writer, if writing
- if root is /dev/root then assume not a ramdisk

01/07 - 02/28
- fixed find_cdrom_device (Stan Benoit)
- if root is at /dev/root/root then LVM (not ramdisk)
- fix am_I_in_disaster_recovery_mode() to recognize that /dev/rd/cp*
  entries are not ramdisks but RAID disks
- find_cdrw_device() no longer complains to stderr if no cdrecord

01/02/2003
- sensibly_set_tmpdir_and_scratchdir() --- exclude smb and smbfs

12/01/2002
- don't ask for isodir path if in disaster recovery mode

11/01 - 11/30
- added g_restoring_live_from_cd;
- handle_incoming_parameters() will sensibly set tmpdir and scratchdir
- properly wipe spurious scratchdir and tmpdir
- modified sensibly_...() to use tmp.mondo.* and mondo.scratch.*
  instead of mondo.tmpdir.* and mondo.scratchdir.*
- line 861,912: set media_size[0] to 1999 as well as 1 thru N
- chmod 700, not 770, in make_fifo()
- sensibly_set_tmpdir_and_scratchdir() will now prefix a '/' to the
  strings if it is missing

10/01 - 10/31
- changed find_cdrom_device() to ignore DVD drives in the hd[a-d] search;
  consequently, the subroutine will try scd0, sr0, etc. afterwards
- commented code
- fixed obscure bug in find_and_mount_actual_cd()
- code which sensibly configures tmpdir,scratchdir is now sep. sub.
- changed sort -s to sort -n <-- sensibly...()

09/01 - 09/30
- added list_of_NFS_devices_and_mounts()
- try /dev/st0 if no tape specified at all
- change '64k' to TAPE_BLOCK_SIZE
- improved find_cdrom_device()
- if cdrecord not found then find_cdrom_device() returns 1
- if disaster recovery mode then don't ask for CD-ROM's /dev entry;
  assume /dev/cdrom
- if restoring data then ask for CD-ROM's /dev entry (not its SCSI node)
- run_program_and_log_output() now takes boolean operator to specify
  whether it will log its activities in the event of _success_
- changed sort -n +4 to sort -s +4 (Troff)
- ask if user's kernel is sane; if 'no' then use FAILSAFE
- ask user to confirm the tape/CD device name
- if restoring (not archiving) then don't try to find CD-ROM's SCSI
  node; try to find its /dev entry instead
- better detection of biggest partition

08/01 - 08/31
- fixed verify bug --- CD#1 was being verified again & again & ...
- detect boot loader + device; if not detectible then _ask_
- if run interactively, assume tape size is irrelevant & don't ask
  for it; Mondo should handle end-of-tape gracefully now
- worked on handling unknowng media size
- added interactively_obtain_media_parameters_from_user()
- when trying to mount CD-ROM, find_and_mount_actual_cd() will
  now call find_cdrom_device() to try to find the /dev entry first
- fixed serious bug in zero_out_a_device()
- cleaned up some log_it() calls
- fixed minor bug in find_cdrom_device()
- better at distinguishing between live filesystem and ramdisk

07/24/2002
