 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
