If we want to stick to the Unix interface, and I strongly think we do
want that, then we'd need to make any translator visible as a separate
file system indeed. On my Debian jessie, the clean_tmp() in
/lib/init/bootclean.sh does use find -xdev, so this would work as

I don't know if that's already the case or not since Justus' work on
/proc/mounts. The work required here is to rely on the parent to report
whether a node is a separate file system. This could also break programs

presents itself as something else.
