Deploying Docker

I have been doing this with schroot's "btrfs-snapshot" chroot type for a few years now without running into a single problem relating to snapshotting/subvolumes. Not that btrfs is stable enough for me to trust for anything but transient snapshots, but that's ideal for this type of usage, and btrfs snapshots are super fast and you can create dozens of snapshots in parallel for e.g. parallel build jobs. I've found them to be more robust than LVM snapshots in practice; rapid parallel snapshotting of LVM LVs will rapidly lock up the kernel (unless it's been fixed in the interim--I just stopped pushing it so hard).

The only Btrfs limitation I've found is the lack of being able to atomically replace one subvolume with another (e.g. if you want to replace the original subvolume with an updated snapshot atomically). In practice you have to do two renames, so it's not atomic.
