Last change on this file since 2731 was 2731, checked in by Bruno Cornec, 13 years ago
  • Adds functions and /bin/loadkeys (new location) to minimal set of commands to have
  • provides a makemessage option to mindi and this function now works with pbdistrocheck
  • Do not create an error when a phys device has 0 size and is a /dev/dm-* device
  • Property svn:keywords set to Id
