I have seen Web pages saying that it boots... I just used google to search grub2 btrfs, and the results don't look promising. Not that you asked, but btrfs is still in development; I wouldn't think that supporting it is anyone's top priority. If you are planning to keep anything important on this system, I'd think twice about using a filesystem that's still in flux: https://btrfs.wiki.kernel.org/index.php/Main_Page Btrfs is under heavy development, but every effort is being made to keep the filesystem stable and fast. As of 2.6.31, we only plan to make forward compatible disk format changes, and many users have been experimenting with Btrfs on their systems with good results. Please email the Btrfs mailing list if you have any problems or questions while using Btrfs. -- monique -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

It is unlikely because /boot/grub contains ext2.mod, jfs.mod, ntfs.mod, ufs1.mod, ufs2.mod, xfs.mod, zfs.mod but not btrfs.mod. Indeed, I see in sources that fs/ does not contain btrfs.c... So it seems that /boot must use another FS for the moment... Well, I will wait...
