Possible patch

Description of problem:

If GATEWAYDEV is set in /etc/sysconfig/network, running system-config-network will remove the option without notice.

Version-Release number of selected component (if applicable):

system-config-network-1.3.99.18-1.el5

How reproducible:

Always

Steps to Reproduce:

1. Add GATEWAYDEV=eth0 in /etc/sysconfig/network
2. Start system-config-network
3. Select File > Save
4. Check contents of /etc/sysconfig/network
  
Actual results:

GATEWAYDEV has been removed

Expected results:

GATEWAYDEV is left unchanged in /etc/sysconfig/network

Additional info:

This is from the fix for bug #78043, in netconfpkg/NCDeviceList.py:

  B<------B<------B<------B<------B<------B<------B<------B<------B<------
       [...]
       # bug #78043
       # we should have device specific gateways
       # fixed this way, until we have a way to mark the
       # default GATEWAY/GATEWAYDEV
       cfg = Conf.ConfShellVar(netconfpkg.ROOT + SYSCONFNETWORK)
       if cfg.has_key('GATEWAY'):
           del cfg['GATEWAY']
       if cfg.has_key('GATEWAYDEV'):
           del cfg['GATEWAYDEV']
       cfg.write()
  B<------B<------B<------B<------B<------B<------B<------B<------B<------

Removing the part that deletes gatewaydev fixes the issue.
