source: MondoRescue/branches/stable/mondo/src/common/libmondo-tools.c@ 1221

Last change on this file since 1221 was 1221, checked in by andree, 17 years ago

Add to Bruno's improvements to function insmod_crucial_modules():

  • Try to load module 'msdos' rather than 'dos' which does not exist. Avoids message: 'WARNING: Module dos not found.' when starting mondoarchive. (Used to be 'FATAL: Module dos not found.' as reported on mailing list when 'dos' was still called in separate modprobe call.)
  • Don't explicitly load module fat - this happens automatically when msdos or vfat are loaded and fat is not useful by itself.
  • Updated the comment accordingly.
  • Property svn:keywords set to Id
