Last change on this file since 2364 was 2364, checked in by Bruno Cornec, 15 years ago
  • More verbose at installation of additional tools
  • Fix a case where the NFS dir in restore mode was mounted rw (linked to bug #291 could create a huge problem)

(backport from 2.2.9)
  • Property svn:keywords set to Id
