First of all,
Thanks for help !
But I do not have any users on the system and it's not going to be any. It's
a Gateway. I want to make it more secure by removing all SUID bits. (Just in
case) I log in to the system every week to check on how things are going,
and that's it.
If I understood you correctly it will affect /usr/bin/login ... Does It mean
I will be able to log in only as root? If so That's all that I need. Will
removing of SUID bits affect root in any way?
Thanks

find / -perm -u+s -print

Daemons?

It will adversely affect some things like /usr/bin/login
