Again, how do you enforce "games are out", "no graphical applications on
this server", "nothing that allows people to chat"? It isn't exactly
Fedora policy (and if it was, what makes you think it will stay

If you need a flexible policy, have a human do it. Not everything can be

And said security flaws will only afect them, not the whole system;
while security flaws in willy-nilly installed stuff affects everybody
(yes, even Fedora-blessed software has had its share of security

One of the basic guidelines when securing a system is to keep it as

strict control over what is happening.  Anything else ends with the
sysadmin in a padded cell.
