I learn something every day! I admit to not using the mod time on
directories much, but I never thought of this. I always thought it was
to allow restoring a directory which is read-only, by creating it by
default (-d) and then fixing the permissions later. I have a few things
in directories which are mode 555 and don't create well on a new system
without -depth. Hope someone else learned something, too.
