Funny... I was in the process of doing almost exactly the same
changes. Initially, I've done this fo /tmp and /var only, because some
software was creating lock files _and_ IPC keys using (obviously) normal
/tmp and /var/tmp, and they ended up having very different values, which
somehow confused it...
Anyway, the solution I would suggest is to have more granularity instead
of all-or-nothing. I'd suggest a linked list of paths, set up by
compat.linux.pathmunge.paths, and the other sysctl to turn on the
checking. If the *paths sysctl is empty, it's equivalent to your
functionality.
Comments? :-)
