Description Ray Strode [halfline] 2009-03-13 17:44:58 UTC 
Right now if /etc/sysconfig/network has

HOSTNAME=localhost.localdomain

then NetworkManager interprets it as a magic string that means "Perform a reverse look up on one of machine's ip addresses and set the internal hostname to one of the external hostnames instead of localhost".  It's a fairly recent change (post F10).

It's a little strange to treat "localhost" specially.  It would probably be better to keep HOSTNAME for specifying a hostname manually and then having some new boolean

DETECT_HOSTNAME=1

or some such that's used for doing the reverse look up logic.  I guess NetworkManager is currently doing it the less intuitive way for historical reasons.  The stack networkmanager supercedes used to do it that way.

Note anaconda sets HOSTNAME to localhost.localdomain in some cases by default.  That issue is being tracked by bug 408921.

Comment 2 Dan Williams 2009-03-23 21:43:37 UTC 
committed upstream; users who wish to have 'localhost.localdomain' ignored and NM to look up the reverse address need to set NM_IGNORE_HOSTNAME_LOCALHOST=yes in their /etc/sysconfig/network file.

Maybe it'snot relayed, but after the latest update to NetworkManager-0.7.0.99-4.git20090324.fc10 it stopped working. Just fails to start network and there's no icon on a panel.
