I installed a server with the "workstation" configuration and simply
"rpm -e'ed" NetworkManager. The result was just fine. The old network
configuration layer is still underneath - the gui is gone though - but
who used that.

| NetworkManager, frankly, has no use on a typical server. Its dynamic
| manipulations of network configuration are unpredictable, unintuitive,
| and far more suited to a laptop or traveling desktop in an environment
| where upstream DHCP is reliably configured. It is a complex and
| powerful tool that *STILL* has no way to configure pair-bonding,
| 'bridged' connections for KVM supporting hosts, or DHCP client
| configuration with client identifiers except to use a text editor and
| turn off NetworkManager by one means or another. It's one of the
| upstream vendors least useful development efforts.
|
| Unfortunately, we're now pretty much stuck with it, due to all the
| recent system dependencies on it. Ripping it out by the roots became
| infeasible with Scientific :Linux 6. Fortunately, pre-configuring
| 'NM_CONTROLLED=no' is a new capability, and doing so early in the
| kickstart '%post' scripts seems to be very helpful in preventing such
| issues. In syntax:
|
| grep -q ^NM_CONTROLLED= [filename] || \
| echo 'NM_CONTROLLED=no' >> [filename]
| sed -i 's/NM_CONTROLLED=.*/NM_CONTROLLED=no/g' [filename]
|
| Deducing the files to do this to is a bit more awkward, since you
| don't want to touch '.bak' files or '~' files, but there are functions
| to do that already available in the /etc/sysconfig/network-scripts/
| utiliti4es. Do you need help with that?
