I didn't immediately spot the place where it was set to "null".
Yes that's a problem, though domainnaming has more restrictions (like using "0" 
(or any other number that is also a domain-id) as domainname) in the "just 
don't do that" category.

From what i remember i also couldn't  use "xl destroy" on such a domain (though 
i probably should by using the domain number instead of the name).
Perhaps the toolscripts should just uses the domain-id numbers instead of names 
for anything except printk's and echoing to the user ?
