zone-mode

[Lars Bungum]

I'm trying to use the zone-mode to update the serial number of a DNS
zone-file from within emacs.

>From what I can read in the docs, the mode should update the serials
automatically when you save the file.  I can't see that this happenes. 
Then I tried to use M-x zone-mode-update-serial to see if that worked,
but wasn't able to get any response back.  No error, but nothing
happenes to the file. 

I don't really know what to do to find out of this (my question).  I'm
not fluent in elisp, but should be able to make something out of
debugging information.

Thanks!
