The btrfs volumes and subvolumes are "not your father's filesystem" 8-) grub2-2.00-12 and -13 in F18 do this correctly already, and automatically. GRUB2 depends on /etc/fstab being properly formed, i.e. includes the proper mount option subvol= in order to know how to create the correct core.img, which has the backed in prefix for grub modules, and also how to create the correct grub.cfg. Unfortunately subvolid= does not work with GRUB2 presently. > I have a little of what is needed working but, the more I look at things, the more it looks like some real kludgy hack is going to be needed to have something which works with /dev/<whatever> to now use UUID=xxx,subvol=name Yes, but if you're using Fedora 18, it does this correctly for you.
