The 's' attribute doesn't appear in the permissions settings until I
suid it, so how can you tell it is already suid root... because dialout
is supposed to be?

My /usr/sbin/pppd is root:dialout. pppd would only work properly when I
'chmod a+s pppd'.
Every time a ran YaST it took the suid off and Kppp wouldn't work until
I put it on again.

This certainly prevents YaST from taking the suid off of pppd so I don't
have to manual reset it every time I run YaST.
So, since you think these two items are problems, why do you suppose
that as a user I can't get pppd to be fired by Kppp unless I suid it?
