source: MondoRescue/branches/stable/mondo/src/mondoarchive/mondo-cli.c@ 1548

Last change on this file since 1548 was 1548, checked in by Bruno Cornec, 17 years ago
  • Add the possibiilty to edit in interactive mode mtab and device.map for grub
  • Remove blkid cache files after restore to avoid problems in cloning mode
  • Fix what seems to appear a huge number of bugs in hack-fstab (illustration of 1 LOC = 1 bug :-)
  • Especially improve LABEL and UUID support.
  • Should fix #185
  • Exclude_path should be 4*MAX_STR_LEN everywhere. Fixed now.
  • Increasing that value will allow to having larger exclude paths.
  • Should solve bug #137 (and maybe #3 as well)
  • Adds support for fedora 7

(merge -r 1533:1547 $SVN_M/branches/2.2.5)
