Hi Jeremy,

I tried running this example from an ordinary account,
and su does ask for nobody's password.
Since none exists (its /etc/shadow entry has a '*'),
I would need to assign one with linuxconf, for instance.
Right?

Actually, I just found a list in chapter 2 of
"The Official Red Hat Linux Reference Guide"
(see
http://www.redhat.com/docs/manuals/linux/RHL-7.1-Manual/ref-guide/s1-users-g
roups-standard-users.html).
RedHat calls them "Standard Users" (and "Standard Groups").
The manual has 2 simple tables merely listing them though,
I have seen no explanation of purpose, rationale, etc.
In fact, they are subsets of the passwd/group files,
and they are not even complete, lacking 'named' and 'apache',
for example.

So you're right, it looks like no detailed documentation exists.

Regards,
Marcel Frechette
