I have two routers for different subnets and I'd like to set up different eth0 configurations depending on which one I have the network plugged into. However, it seems that every time I let system-config-network do its thing it forces all the eth0 configurations to be the same (hard-links them all to the one in the "default" profile).

I'd also like to have virtual interfaces configured differently in different profiles -- as in, not configured at all in some profies -- so I tried creating e.g. ifcfg-eth0:1 in one of the profiles/ subdirectories, but not only is it ignored when using the network control tool to switch profiles, it also gets *deleted* from the profile if I run system-config-network.

There's nothing about profiles in /usr/share/doc/initscripts-7.93.20.EL/sysconfig.txt and no documentation included with the system-config-* RPMs. Does this simply not support having different devices in different profiles? This (particularly the deleting of files I hand-edited) is the sort of thing that used to make me rip linuxconf out of the older RedHat distributions.

On a similar note, my ISP has four nameservers, plus I want to include my local LAN nameserver and the nameserver from my work network -- but system-config-network insists on deleting all but the first three nameservers from my resolv.conf. Yeah, I know, upstream issue, but as long as I'm venting ...
