source: MondoRescue/branches/2.2.4/mondo/src/mondoarchive/main.c@ 1437

Last change on this file since 1437 was 1437, checked in by andree, 17 years ago

New define 'MINDI_CACHE' set to '/var/cache/mindi' rather than
hardcoding this in the code. Makes it easy to change the location. Also
adjusted some of the messages related to boot floppies or CDs.

(Also added missing debug level to log_debug() call.)
