Grub-0.97+btrfs doesn''t understand exotic things like preallocated extents (e.g. files composed by fallocate(2), posix_fallocate(3)). Also grub-0.97 doesn''t check btrfs checksums. In such configurations btrfs_stage1_5 doesn''t exceed 62 sectors in size and can be installed to the boot area. Technical overview: Things are complicated because of logical/physical block translations. We can not afford to maintain a long cache, so grub will search like a mad. The main search routine aux_tree_lookup() is rec...

...tage 1.5 file) and stage 1.5 first sector (list of all > other sectors)? > Grub doesn''t make the blocklist for stage1_5 Optionally grub makes the blocklist for stage2 (in particular when stage1.5 can not be embedded for some reasons). Note, that it is important to embed and use btrfs_stage1_5. First, because btrfs has defragmentator, which can make the blocklist out of date (so that you''ll need to reinstall grub). Second, I am not sure, if the blocklist will be composed correctly in the case when stage2 locates in btrfs volume (I didn''t look at the blocklist specificat...

Hi, The following patches add support for ext4 and btrfs to PV-GRUB. These patches are taken nearly verbatim from those provided by Fedora and Gentoo. We''ve been using these patches for the PV-GRUB images available in EC2 for some time now with no problems. Changes from v1: - Makefile has been changed to check the exit code from patch - The btrfs patch has been rebased to apply
