ooh. ok so make zomebiefs kinda like nullfs. You can clone a mountpoint (but it's "empty"), and when you delete files at the origin they appear in the zombiefs version. And they aren't released / fully deleted until the zombiefs deletes it as well or is unmounted.

edit: I think I just described the Trash/Recycling Bin ...

@feld Yeah, I think that's more `necrofs`.

For `zombiefs` I want to say that it's a file system where you can delete files as much as you like, but they never disappear.

But...it could be mistaken for a file system that just will not die, and you keep seeing everywhere, even if it has no right being used anymore. The usual name for this is fat32.
