Description of problem:
When s-c-n starts, it seems to read the system's hostname as
localhost.localname, even if a different hostname is set in sysconfig/network or
by dhcp. When any network changes are committed, the hostname is changed to 
localhost.localdomain, potentially breaking sudo, X and any other
hostname-dependant services.

Version-Release number of selected component (if applicable):
1.3.95

How reproducible:
Always

Steps to Reproduce:
1. Run s-c-n
2. Look at the dns settings. Host should be localhost.localdomain
3. Add a network interface or anything else that requires saving settings
4. Save settings and close s-c-n
5. Run hostname. 
  
Actual results:
Hostname should be original value unless explicitly changed in s-c-n

Expected results:
Hostname is localhost.localdomain

Additional info:
This was reported to me by someone else and I then verified it, so it's not just
my system.
