So two ways from there to improve the situation:Make the locking executables setgid or setuid.
(and have just one executable doing the locking.)
And/or use the /tmp directory.Localise all global lockable resources.
(Unlikely to work.)Bernhard
OK. This looks, then, like a situation which is dependant on the local
environment. With xterms off a central server I can see the problems.
With a bunch of networked PCs (what we have here) it may be less of a
difficulty.
I would not like to have the executables be more "powerful," so localizing
locks would be a better solution. Perhaps this could eventually be a
configuration option. Of course, there likely are more important things
to worry about. :^)
Thanks for your time.
Adios,
Chris
