describe the request
Currently, it is possible to change the mount point of the ESP partition to something else than /boot, like /efi by manually editing the partition layout.
But doing so, it becomes impossible to enable BTRFS snapshots.
I believe the problem is that the has_default_btrfs_vols method which is called by the _check_dep_btrfs method is too restrictive.
I don't know why this check is done like that. Maybe only checking if there is at least one BTRFS partition would be enough ?
