Hi,
I'm using a /boot partition in ext4 for booting with grub, which is then bind
mounted into a btrfs root partition:
---
lapix:~# mount |grep hda
/dev/hda2 on / type btrfs (rw,ssd)
/dev/hda1 on /media/hda1 type ext4 (rw,relatime)
/media/hda1/boot on /boot type none (rw,bind)
/dev/hda3 on /media/hda3 type btrfs (rw,ssd)
---
Installing grub on this setup using
---
grub-install /dev/hda
---
completes, but the resulting boot installation fails to boot grub.
Upon booting I was only arriving in the grub rescue mode - probably the
actual /boot/grub files weren't found.
Installation works and is booting Ok, when using grub-install as followed:
---
grub-install --root-directory=/media/hda1/ /dev/hda
---
Maybe the problem is, that during installation on a bind mounted /boot/grub
directory, the actual place of /boot/grub is not correctly determined ?
Apart from that, I had also to apply the patch from following bug posting
thread, to complete the debian grub-pc 1.98-1 package update on my btrfs
setup:

In case of more info needed, just tell.
Cheers, Oliver
