[Centos] Secure server install

[centos at kral.no (Håvard Hebnes)]

Not sure if this is the right place to ask, but I'll try.

When I do a minimum install of Centos, which default users should I delete (users that won't be needed on a
server) It will be used for webhosting, mail, sql.. And, what partitions would you advice me to create? /root,
/tmp, swap, /... should I have more?
