svn merge -r 2586:2634 ​svn+ssh://bruno@svn.mondorescue.org/mondo/svn/mondorescue/branches/2.2.9

  • Avoids error messages from stat in analyze-my-lvm
  • Avoid perl warning by removing non-exitent dirs from @INC in mindi-get-perl-modules r3744@localhost: bruno | 2010-03-16 01:44:33 +0100
    • Fix a bug on Mandriva modules analysis (at least) (Backport from mindi 2.1.0)
  • Try to improve exclusion of binded /proc mount with "none" fs type exclusion Cf: #397
  • Adds gmane mirror on the support page of the web site.
  • More website improvements based on Tom Metro feedbacks
  • Adds Nable ML archive
  • For gmane prefer the threaded view to the blog one.
  • Fix an initialization bug for network protocol in interactive mode (was NULL and not NFS by default)
  • Put an explicit notice of MondoRescue's license: GPLv2 or later (as per Hugo's notice in sources)
  • Adds tee to deplist
  • Fix #412 by supporting grub-install.unsupported for OpenSuSE and solving an issue with the parameter passed to grub for device which should be a device name, not a partition.
  • Fix #413 where list of devices was not re-initialized correctly in a loop (Michael Shapiro)
  • Fix #415 by avoiding integration of unknown devices report from pvscan (Mike Shapiro)
  • Fix #414 by adding a function GetPVsForLV to remove PVs from excluded LVs (Mike Shapiro)
  • Fixes for #414: remove comments from grub conf file if used and improve grub conf file generation
  • Fix a typo (Mike Shapiro)
  • Improved msg for USB device creation
  • Mondoarchive should not try to cerate a cmp binary if it doesn't exist.
  • Fix a bug on ia64 where the boot image generated was removed before use in mondo
  • Avoid to have multiple similar calls to mkisofs by using macros r3946@localhost: bruno | 2010-05-04 19:17:51 +0200
    • Solves an issue with usage of -V option in mkiofs wrongly placed
  • netfs_proto should be initialized in every case, not just in DR (should solve remaining NULL reports)
  • Integrate Michael Shapiro's patch on Xen Kernel support for RHEL 5 (only atm) and fixes #418 (Michael Shapiro)
  • Fox a typo in a Web page
  • Precise that GPL is v2+ (as per Hugo's wish)
  • Improve display of messages (removes extra \n) and replace a stract with "" with " ". trying to debug #421
  • Remove a wrong usage of mr_strcat with exclude_path in the 2.2.9 version (probably cause of #421)
  • Fix strcat call !
  • Property svn:keywords set to Id
