Bug#540786: update-grub/grub-mkconfig doesnt work with btrfs as rootfs

[Vladimir Stavrinov]

Package: grub-common
Version: 1.96+20090808-1
Severity: normal


The same problem exists in diskless and chrooted environment.

chroot is done onto logical volume, while root directory is partition on
physical device, but both filesystems is ext3. It break chrooted system
upgrade process with error:

grub-probe: error: cannot find a device for /.

that is output of

grub-probe /

calling by update-grub from postinst script.

In case of diskless workstation the root fs is aufs based on cifs.
