Quotes of the week
This feature can be replicated for any subdirectory, where the parent holds multiple snapshots of said directory. There is no global snapshot table per-say.
This makes it possible to trivially construct and maintain multiple mirroring domains within any subdirectory structure. For example you can construct a HAMMER2 filesystem which holds multiple roots and then mount the desired one based on a boot menu item, and you can work within these roots as if they were the root of the whole filesystem (even though they are not).
