source: MondoRescue/branches/3.2/mondo/src/mondorestore/mondo-prep.c@ 3292

Last change on this file since 3292 was 3292, checked in by Bruno Cornec, 10 years ago
  • Remove from mindi 2 functions replaced by perl code (ReadAllLink by mr-read-all-link and ProcessLDD by mr-process-ldd)
  • Redirect mindi execution to mondo log on the fly to try to improve percentage display with newt (not finished yet)
  • Introduce a new global var MINDI_LOGFILE and use it everywhere
  • Fix some memory free mising (thanks valgrind)
  • Remove a call to rpm to log packages - not portable
  • Works with valgrind locally to create images in dir
  • Property svn:keywords set to Id
