Package: grub-pc Version: 2.02-2 Severity: normal
Hi. I've noticed the following: When I have a btrfs fs, which is e.g. mounted and /mnt/ and a subvol at /mnt/root ... and that subvol contains a Debian image... Then one typically does something like: cd /mnt/root/ mount --bind /dev/ dev/ mount --bind /proc/ proc/ mount --bind /sys/ sys/ chroot . grub-install --no-floppy --recheck /dev/sdX in order to make the device bootable. This however fails with: Installing for i386-pc platform. grub-install: error: cannot find a device for /boot/grub (is /dev mounted?). The problem seems to be that one is located in the subvolume. E.g. when unmounting all the above, and repeating it with the subvolume mounted at /mnt, i.e. mount -o subvol=/root /dev/sdX1 /mnt/ … the process works. Perhaps it can be made working out of the box for all cases :-) Cheers, Chris.
