This is approximate.  flames >/dev/null

daemon  Owner of print despoolers and other automatic processes
sys     Owner of some SYStem stuff
bin     Owner of most of the system BINaries
uucp    Unix to Unix CoPy program -- dialup email and news transporter
news    The news system

Your mileage may vary, especially as to finding files and/or processes
which are actually owned by the first three of these.  In some systems,
most such files and processes are owned by root instead.

The * will not match any possible password, thereby preventing logins to
these "user" id's.
