[Bug 1329810] Re: Btrfs /boot partition has no UUID

[Chris Murphy]

Using ubuntu-14.04-desktop-amd64.iso installing with a custom layout to
UEFI VM, partitions are EFI System partition (vfat), boot (btrfs), and
root (btrfs), with no swap partition, each btrfs volume has a UUID and
it's used in the fstab. So I can't reproduce this bug.

Title:
  Btrfs /boot partition has no UUID

Status in “ubiquity” package in Ubuntu:
  New

Bug description:
  Do the following to reproduce the problem: Using the installer create
  a /boot partition (primary) using btrfs as file system. When the
  install is finished and you boot up the system, the fstab entry for
  /boot looks like this:

  /dev/sda1 /boot btrfs defaults 0 2

  This does not happen if I repeat the exact same procedure using
  ext2/ext3/ext4 for the /boot partition, where an entry in the
  resulting fstab looks like expected:

  UUID=13b5e56a-825c-4633-bd65-64174ecc3c7b /boot ext4 defaults 0 2

  I tried to manually solve this issue by running

  "sudo blkid /dev/sda1", but nothing is returned and "sudo blkid" does
  not list /dev/sda1 anywhere.

  There is a reason partitions should be mounted by UUID and not by
  /dev/sdXY, because under certain circumstances the partition will not
  be found.
