No, there is a bit in the subvolume metadata that says whether it's considered a snapshot or not. Internally, they are handled identically, but it does come into play when you consider things like btrfs subvolume show -s (which only lists snapshots), which in turn means that certain tasks are more difficult to script robustly.Austin S Hemmelgarn wrote (ao):What's wrong with "btrfs subvolume snapshot"?Well, personally I would say the fact that once something is tagged as a snapshot, you can't change it to a regular subvolume without doing a non-incremental send/receive.A snapshot is a subvolume. There is no such thing as "tagged as a snapshot". Sander
