Description of problem:
Using the latest test version dhcp-4.0.0-20.fc9 and related packages, after stopping and restarting eth0 with s-c-n, the selinux permissions on /etc/resolv.conf are wrong:

-rw-r--r--  root root unconfined_u:object_r:net_conf_t:s0 /etc/resolv.conf

This was originally filed in bug #451560 against dhcp, but was advised there that with the latest test version of that component, this is now a new problem with s-c-n.  My OS was fully updated with the exception of using the test version of dhcp when I tested this.

Version-Release number of selected component (if applicable):
system-config-network-1.5.10-1.fc9.noarch

How reproducible:
always

Steps to Reproduce:
1.  Boot.  At this point the permissions on /etc/resolv.conf are correct.
2.  Stop eth0 with s-c-n.
3.  Restart eth0 with s-c-n.
  
Actual results:
Selinux permissions on /etc/resolv.conf are now

-rw-r--r--  root root unconfined_u:object_r:net_conf_t:s0 /etc/resolv.conf

Expected results:
Permissions should be same as before, namely

-rw-r--r--  root root system_u:object_r:net_conf_t:s0  /etc/resolv.conf
