Description

Currently, the auto backend logic is exclusive for backing filesystem:

// +---------+--------------+------------------------------------------+
// | Backend | Suggested on | Disabled on                              |
// +---------+--------------+------------------------------------------+
// | aufs    | ext4 xfs     | btrfs aufs eCryptfs                      |
// | overlay | ext4 xfs     | btrfs aufs overlay overlay2 zfs eCryptfs |
// | bind    |              | N/A(`--sandbox_directory' must exist)    |
// | copy    |              | N/A                                      |
// +---------+--------------+------------------------------------------+

This might cause unstable issue on some specific backing fs. An inclusive logic should be supported. See:
