svn merge -r 2773:2849 2.2.9 in 2.2.10

  • Adds 3 binaries called potentially by udev o support USB key mount at restore time (Victor Gattegno)
  • Really support both mkisofs and genisoimage everywhere
  • Try to handle netfs_user better in all cases (NFS and SSHFS)
    • Improve logging in init script
    • Format improvement
    • Removes a warning when trying to launch udevadm and it doesn't exist (RHEL 5 e.g.)
    • Fix syntax description in mondoarchive man page for -E & -I with |
  • Adds download entries for new distro supported (Mageia, Fedora 15, Ubuntu 11.04)

-Fix mindi-get-perl-modules when perl dirs in @INC are symlinks (case on Ubuntu 11.04)

  • Fix option --findkernel in case of Xen kernel so that mondoarchive get a correct answer instead of an empty one.
  • Fix multi-media restore by umounting it before looping to ask for the next (as if already mounted, will not pass to the next alone)
  • Fix 485 by replacing a wrong call to mr_asprintf which was provoking core dumped.
  • Fix -E and -I example in man page which were lacking the '|' as separator
  • Fix #484 by adding support for the arcmsr driver (to support the Areca ARC-1220 RAID Controller)
    • Avoids error msgs if no mondo-restore.cfg file exists (when mindi used stdalone)
    • Adds the swapon feature to mindi-busybox
    • Attempt to fix Xen kernel support by avoiding to remove xen kernel fro; the possible_kernels list too early, whereas it's used afterwards to get them.
    • Fix #481 by supporting the new kbd file in latest Ubuntu 10.10+ (victor.gattegno_at_hp.com)
  • Update from Lester Wade on P2V doc including RHEL6 validation and some minor additions
  • removes telinit call in busybox o try to fix problems whn reboot at end of restore.
  • if -E option for mondoarchive was not specified, variable excp points to NULL, so string exclude_pathes contained '(null)' instead of being avoided (derived from a patch from taguchi_at_ff.iij4u.or.jp)
  • fix -maxdepth option for find command. it sould be '-maxdepth .. -name ..', not '-name .. -maxdepth ..' (patch from taguchi_at_ff.iij4u.or.jp)
  • Adds an extraversion for revision support
  • Adds support for ifconfig and ping for PXE+NFS boot for this version of mindi-busybox
  • Example of MINDI_ADDITIONAL_BOOT_PARAMS in mindi.conf added
  • fix a compilation error
  • Remove an absolute ref in the docs web page
  • Property svn:keywords set to Id
