I apologize if I've missed it somewhere, but does grub support booting
from a multi-device btrfs root sub-volume without a separate /boot?
According to the wiki I think it's supposed to work, but when I chroot
to that root, and run grub-install, it returns:
Path `/boot/grub' is not readable by GRUB on boot. Installation is
impossible. Aborting.

I left the chroot, and installed grub to that disk from my old root,
but it won't boot from my new volume. Does anyone have some advice,
or should I just move to a separate /boot?

Thanks,

Hi, I have just finished an installation of archlinux onto a btrfs
partition (although it is not a multi-device btrfs partition) with /boot
in a separated subvolume. For my case the grub2 works well. Before your
running of grub-install, have you checked if /root is accessible from
your chroot environment?

I have a btrfs partition (no seperate /boot) and I recommend using
syslinux. You won't even have to upgrade to Grub2.

Well, I'm trying to migrate an existing install that is already
booting from grub(2). I could have sworn that I read that syslinux
didn't support booting from a non-separate /boot btrfs partition. I
suspect it's the multi-device part that's the issue. I'm just going
to try, again with a separate /boot partition, and see how it goes.
