NetworkManager is handy for a laptop where you want to deal with
different wifi settings and moving around among dhcp networks, but for
servers you probably don't want it to overwrite your static configs
and /etc/resolv.conf, etc. I've usually let it install but then
service NetworkManger stop
chkconfig NetworkManager off
to keep it from running when I set static configs. I'm not sure what
happens if you don't install it at all - that would probably be even
better.
