source: MondoRescue/branches/2.2.10/mondo/src/common/libmondo-cli.c@ 2444

Last change on this file since 2444 was 2444, checked in by Bruno Cornec, 15 years ago
  • priority given to env var for tmpdir
  • fuse FS excluded from tmpdir computation
  • Improves udev timeout handling
  • fuse device is needed at restore time for sshfs
  • Avoids comment analysis in the new code handling deplist.d
  • Avoids error message if some ssh conf files do not exist
  • Improvements on sshfs/ssh management in restore mode
  • Include now all minimal requirements for sshfs
  • Fix udev support in init for Mandriva 2009.1 (udevadm settle is blocking)
  • Improve deplist.d/* files
  • adds libnss for ssh support in boot disk
  • Solve a memory management issue in DSF module (strtok => mr_strtok)
  • DSF now also supports partitions in addition to full disks
  • Adds debug in open_and_list_dir
  • Improve user management for NetFS cases
  • ssh in the restore env needs some dlopened libs (libnss_compat|files)
  • Warning emited in case of duplicate mountpoints or devices in fstab found
  • Use only the AWK veriable everywhere and not the awk command
  • Simplify GetInitrdFilesystemToUse which doesn't need to detect everything, but just know if it's initramfs (new mode) or a compressed FS ext2/3 (older mode) as initrd is anyway re-made by mindi. Should fix #353

(Backport from 2.2.9)
