It's pretty simple -- if one tries to add a static route, the gateway for that route will overwrite the default gateway in /etc/sysconfig/network, even though the default gateway _is_ specified on the same netcfg screen.

This is fixed in netcfg-2.24, which will be in the next release of Raw Hide. Please reopen this bug if you continue to see this problem after upgrading.
