Still not kosher; there might be multiple roots on a system ...
What do you suggest, then? Leaving things as they are makes it impossible
to do a clean shutdown of an APRP system if the kspd was last used to
an RP binary that was read from a mounted file system. I respectfully
that it's at least an order of magnitude more likely that a mounted file
will have been used than a chrooted, mounted file system.
