Description of problem:
Changing a host name in the Hosts tab and then using File->Save results in a corrupt /etc/hosts file. The entry for the host you renamed won't appear in the host list. Things get even more messed if you continue renaming hosts and saving after that.
There's a logic error in how the host profiles are saved. Look in NCProfileList.py for ...
# delete all other entries the user has deleted in the UI
..and think about the case when a host is renamed, since all of this logic is driven by host names.
It turns out, however, the if you save _twice_ after editing, things will work out OK - so the following patch appears to work-around the problem.

Steps to Reproduce:
1.Go to the Hosts tab.
2.Add some hosts
4.Look in /etc/hosts, and you should see your new hosts
5.Now, pick a host and hit Edit.
6.Change the host name (I've been changing the aliases as well, but that probably has no impact)
8.Look in /etc/hosts again, and you should be missing an entry
10.Look in /etc/hosts and it should look OK.
I can reproduce with redhat-config-network in RHEL3. It's probably also in other releases.
I see this problem hasn't been fixed yet.
While trying to reproduce it on the latest rawhide, I noticed that you have to
have more than 1 entry in the host list (apart from local host) to reproduce.
Create entries for "foo", "bar", and "baz". Save & Exit. Then restart, rename
"bar" to "gar" and Save. Look in /etc/hosts and you'll only see localhost, foo
and baz. Save again and gar will appear.
This is still a bug in FC5. I've updated the Version to FC5. Is that the right
thing to do?
