Bug#595458: /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?). [btrfs]

[Alexander Kurtz]

Hi Nicolas,

Can you contact me directly via Jabber (kurtz.alex at googlemail.com)
within the next hour or so? This would make debugging a lot easier!

If not, could you please (in this order):

 * check wether you use any sorts of RAID/LVM/CRYPTO etc.
 * attach the content of /etc/mtab
 * attach the content of /boot/grub/device.map
 * attach the output of these commands
      ls -l /dev/root
      stat /
      stat /boot/
 * swap the first and second line of /etc/fstab (/boot and /) 
   so that / is before /boot, then reboot and try if update-grub works
 * try to regenerate /boot/grub by using
      mv /boot/grub /boot/grub.backup
      dpkg-reconfigure grub-pc

Best regards

Alexander Kurtz
