That much I know. They can affect how *they* use their account, but can
they affect the "system"? i.e. What the computer does in their absence,
and how other users use it?
Sure, I can stuff up my .bash* files, and make it impossible for me to
use my account properly. But the next person to log on isn't using my
account, and isn't affected by my mangled .bash* files. The question is
can I do something to my personal files that isn't restricted to my own
use of a system?
