I apologize for the extremely late reply to this, as I don't read the 
fedora-xen list archives as often as I should.   This one snuck past.   
In general, cobbler discussion happens on et-mgmt-tools at redhat.com -- 
all emails to that list (or submissions to cobbler's bugzilla component) 
will definitely catch my attention.  

This will be fixed in 0.3.5 -- which I'll push this out this week.  

Thanks,
