When are users going to need *1000* executables? In a "standard"
corporation / SME / whatever I would expect most people to only need up
to 20 to do their day to day work. As for those 1000 users, there will
be entire swathes of them that have the same requirements because they
essentially carry out the same task or do the same job, so they are
effectively just the one users... suddenly that million element control
matrix looks a lot, lot simpler.
I mean whitelisting this isn't trivial, especially for hosts, if it was
we'd all be using SELinux by now, but at the moment Marcus looks like
the special guest at a scarecrow convention, what with all the straw men
being thrown his way...
