On: The Btrfs inode-number epic (part 1: the problem)

[magicalhippo]

I'm no expert so maybe I'm missing something.

To me it seems that ZFS snapshots represents a similar challenge[1] given that the snapshots can be accessed through the .zfs directory, and that ZFS also plays tricks[2] with the inodes.

They're always explicit mounts on ZFS. (Even the .zfs directory triggers mounting on access of things under snapshot/.)

As a tangent, what's interesting is whether `mount` shows the mountpoint.

If you cd into a snapshot on FreeBSD it does not get listed in calls to `mount` but does on ZoL.

edit: i have not tested this since FreeBSD rebased on ZoL
