Hi,

Any idea about auto export multiple btrfs snapshots?

One related patch is yet not merged to nfs-utils 2.5.3.
From: "NeilBrown" <neilb@suse.de>
Subject: [PATCH/RFC v2 nfs-utils] Fix NFSv4 export of tmpfs filesystems.

In this patch, an UUID is auto generated when a tmpfs have no UUID.

for btrfs, multiple subvolume snapshot have the same filesystem UUID.
Could we generate an UUID for btrfs subvol with 'filesystem UUID' + 'subvol ID'?
