Grub can boot kernels off of a btrfs system. It has modules for
that. There should have been an insmod line in your boot entry where you
tell Grub to load the btrfs grub module, similar to how you might have
had one to load its ext2 module. Then you would have needed the linux
btrfs module loaded into linux at initrd time so it can mount root from
btrfs.
It does work. I have a debian system system set up this way. In fact I
plan to install Slackware 15 into that same btrfs filesystem somehow
without reinitializing it, with slackware root being mounted from a
btrfs subvolume while keeping the existing debian on the same filesystem
intact and also bootable. I may be too optimistic, but I don't see any
of this having much to do with Slackware. It should be happy with
whatever filesystem I give it, the problem being between me and
grub/btrfs. Should be no problem, right?
