The module wrote the configs and the timers, but nothing creates the
.snapshots subvolumes they need, so snapper-timeline failed every hour
with errno:2 and there was never a single snapshot to roll back to.
Removing it rather than fixing it: rollbacks of / are already covered by
NixOS generations, and snapshots of /home would have shared a disk with
/home. That answers "I deleted the wrong file" but not "the disk is
gone", and the second is the failure that actually occurred here.
