Last change on this file since 1236 was 1236, checked in by Bruno Cornec, 17 years ago

Port from stable important patches for 2.2.2:
mindi-busybox:

  • Improve Gentoo packaging

mindi:

  • Better messages for analyze-my-lvm
  • Add support for newer Qlogic drivers (qla2300 & 2400), mpt, dm and ohci
  • Fix a bug in mindi for the FAILSAFE support
  • PATH fixed for init in restore (/usr/games added for petris)
  • Fiw a bug where restore failing because no archive files are found when -G is used
  • /media is now completely excluded as per StandardsCompliance

mondo:

  • Handle no compression + verify correctly
  • various HOWTO fixes
  • Fix temporarily a bug when a biggiefile > 32MB was compressed below the size

of a slice (16MB)

  • Better module loading in insmod_crucial_modules
  • Improve Gentoo packaging
  • Small typo fix for mondorestore man page
  • Small memory management improvements
  • Store NFS config only once
  • Fix a flaw in libmondo-mountlist.c (there since rev [1] !!)
  • Increased MAX_STR_LEN to 384 to make it divisible without remainder by eight

for 64 bits platforms

  • Fix a bug where no bzip2 format file would be found when supporting gzip
  • CentOS fixes
  • Property svn:keywords set to Id

608/01
7- when evaluating mountlist, skip drive entirely if it does not exist
8
907/14
10- always exclude /devpts, /proc, /sys from mountlist
11
1206/29/2004
13- changed some char[] to *char
14- drivelist is struct now, not char[][]
15
1610/19/2003
17- format_device() --- contract /dev/md/N to /dev/mdN to
18 overcome devfs problems
19
2006/11
21- added support for 5th column in mountlist.txt, for labels
22
2305/08
24- added save_mountlist_to_disk() and load_mountlist()
25 and misc other funcs from mondorestore.c
26
2705/05
28- added Joshua Oreman's FreeBSD patches
29
3004/24
31- added some assert()'s
32
3304/23
34- cleaned up evaluate_drive_within_mountlist() a bit
35
3601/15/2003
37- added code for LVM (Brian Borgeson)
38
3910/19/2002
40- added some comments
