source: MondoRescue/branches/stable/mondo/src/mondorestore/mondo-rstr-tools.c@ 1326

Last change on this file since 1326 was 1326, checked in by Bruno Cornec, 17 years ago
  • MONDO_LOGFILE is rather a char* exported by each main program (consolidation of those mecanisms in .h files with ps_*)
  • One include has been created for each binary containing only the specific declarations
  • Log files are now consistent: mondoarchive.log for mondoarchive (containing also mindi.log) and mondorestore.log for mondorestore (copied from /tmp (ram) to /var/log (disk) at the end of the restore)
  • Doc updated accordingly
  • LOGFILE in restore process is now passed in the environment and not duplicated a nymore
  • LogIt is not redifined either
  • LOGFILE should be put in environment by mondoarchive for mindi's usage but that's a step left for later.
  • label-partitions-as-necessary should now work correctly for LABEL and UUID (grep -w removed)
  • Remove useless script compare-me

(All coming from 2.2.2) (remains changes in my-stuff.h coming later on)
  • Property svn:keywords set to Id
