Yes, that is exactly what I meant, which would make sense in the
context of the first part I suggested:

	- Take a snapshot without mounting it:

		# snapfs /home /home/.snap/20260718

Yes, that would also be nice.  If /home is not ffs, it would need a
temporary place for the storage to go, something like:

	mount -t snapshot -o snapstore=/var/tmp /home /mnt
