I'm sure there's a bash-app for that...

*sigh*

And here I thought it was as simple as setting a flag on disk.

Sounds like the implementation lends itself to having an extended-attr
to potentially set the option on a dir-by-dir basis 
similar to the +d bit, though it would only apply to dirs and files
within -- but not subdirs (due to different mount locations)?

That might certainly be more flexible than a whole disk as well if it
is practical.

Then as the 'attr' was set, the hash could be rebuilt either inplace,
or created as a newdir with files being moved to the new dir.
