Last change on this file since 2696 was 2696, checked in by Bruno Cornec, 13 years ago
  • Adds preliminary support for hpacucli. Needs test
  • Fix a compilation issue due to bad fatal_error call (no param allowed)
  • Fix some HTML syntax issues in the docs page + link to Wiki articles
  • Boot size pushed to 20MB
  • A bit more precise for error msg from PBDI
  • Exits if the protocol used is not recognized (error with -n fs:// typo)
  • Adds support for r8169 net driver
  • Fix a cast issue
  • Precise a test case to avoid ambiguity
  • Die and related functions placed before any other code as used early, and ash doesn't support function declaration. So will solve #446 by exiting mindi before doing anything weird in it.
  • Fix #445 with another technical solution to avoid vg with similar names to b wrongly excluded (vgroot and vgroot-san e.g.) (Michael Shapiro)
  • Fix a bug on exclusion of path with common content (/home and /path/home e.g.) which was handled correctly only in a certain order (John Pearson <johnp_at_gtagalenco.com.au>)
  • mount-media function is now placed in libmondo-devices.c as used by more programs.
  • Avoids calling mount_media when it's not mandatory (change the way mondorestore was working up to now but could solve some bugs reported)
  • Add xhci support to mindi.
  • Rewrite Xen kernel support to use TryToFindKernelPath systematically.
  • mindi now copies also the /lib/firmware content in order to have it for drivers needing it (bnx2 reported)
  • Push MAX_STR_LEN to 512 to allow supporting more exclude dir (2.2.10 and dyn allocation is the way to go there)
  • Add virtio driver to mindi
  • Initialize extra_cdrom_params in any case tp avoid passing null to cdrecord later on
  • Also escapes white spaces in gen_aux_list to avoid issues in getfacl call
  • Adds multiple missing drivers to mindi (mega_sr, ide_gd_mod, pata_jmicron, cp210x, dca, raid6_pq, xor async_tx, async_memcpy, async_xor)
  • Fix #434 by really testing thet udevd is not running already (chucky)
  • Adds support of pata_sil680 driver
  • Fix again #412 !! by removing calls to tee which voids the return value of the previous command
  • The way grub.unsupported was called for opensuse 11.2 was wrong. It should be done bfore calling grub-install which also exists. And tested for existence. Now this should fix #412.
  • Try to provide a workaround in code to the #401 (over-allocation of space due to rounding errors)
  • Fix a bug when using ACLs and file with spaces in their names by adding double quotes in getfacl invocation (Tom Mortell tomm_at_dslextreme.com). Also adding the same quotes on the touch commands made earlier.
  • Points to the current latest presentation instead of the old one
  • mondo-ref-card added to the docs web page
  • Add the mondoarchive reference card (Lester Wade)
  • Change useless comments for more useful ones
  • mindi is now able to handle compressed kernel with .gz or .bz2 suffix (case of OpenSuSE 11.2)
  • Improves logging for external binary
  • Improve Xen kernel detection and avoid false detection (Michael Shapiro)
  • Updated P2V doc from Lester Wade (lester.wade_at_hp.com)
