I've never needed it for a domu either, never-the-less, the facility is 
there :)

My only use of the option is also in my dom0 to prevent sd0 from overriding 
wd0 on boot.

Hey, I said I was considering it! :)

I can see your intention but I don't think everyone would agree that it's 
classed as polluting. You can set mk.conf and rc.conf options to accommodate 
rc scripts outside of /etc/rc.d. Incorporating something like this into a 
some kind of native xen distribution might be useful but as is, you still 
need to declare the relevent variables in rc.conf with the only side effect 
being that the xen services fail to start on a non-xen kernel.

The problem with the docs isn't so much about addition as it is about 
modification and subtraction ;)
