source: branches/2.2.6/mondo/src/mondoarchive/mondoarchive.c @ 1967

Last change on this file since 1967 was 1967, checked in by Bruno Cornec, 12 years ago
  • Remove all references to /root/images
  • Fix the lack of support for options in mondorestore by copying what is done for mondoarchive and sharing the functions analyzing the cli (getopt usage)
  • Review the now common handle_incoming_parameters to have it support correctly 2 modes (archiving and restoring)
  • Update mondorestore man page to take in account the options supported now
  • Replace mondorestore options --nuke, --interactive, with -Z nuke, -Z interactive ...
  • Property svn:keywords set to Id
