This makes sense, but I did not succeed to use mount_nullfs on an 
5.3-RELEASE/amd64 machine, while the same worked well on my 6.1/i386 
computer, so I'm not sure mount_nullfs is reliable enough on older systems.
Also, other targets should be supported as well, and the nullmounted 
directory should be umounted after he run. Anyway, I find this solution 
very good, if we can work this out a bit better, my progress so far 
would become pointless...
