source: MondoRescue/branches/2.2.4/mondo/src/mondoarchive/main.c@ 1375

Last change on this file since 1375 was 1375, checked in by Bruno Cornec, 17 years ago
  • ARCH removed from configure.in as useless
  • addition of get_uname_m (to give the underlying arch)
  • get_architecture now returns correctly the built arch used (including x86_64)
  • IA32 is defined for both i386 and x86_64. An additional vdefine X86_64 is also setup for tha later arch.
  • Property svn:keywords set to Id

46
4709/23
48- added some comments

82 whether it will log its activities in the event of _success_
83- added popup list of changed files
84- removed 'beta-quality' warnings
85- if kernel not found and mondo in graphics mode then popup and ask

88- unmount and eject CD at end of verify cycle
89- moved interactively_obtain...() to libmondo-stream.c
90- wrote stuff to autodetect tape+cdrw+etc.
91- renamed from main.c to mondo-archive.c
92- fore+after warnings that this code is beta-quality
93- abort if running from ramdisk
94- remount floppy at end & unmount at start if Mandrake
95- took out #debug stuff
96- add 2> /dev/null to 'find' command
97- add support for bkpinfo->nonbootable_backup
