Eh. Thanks for the mention... gave it a shot, but it seems to fail
nearly immediately:

I guess that means it won't work on an ext4 fs. :-)
I did create a snapshot of it using LVM (durr, I didn't think of that
before) so the FS is preserved as it was... I just don't know how to go
about digging through it to get the directory that I deleted out.
Hopefully I can figure that out before terribly long, as I am stuck
until I do...
