Hi,

The intent is to discover whether there's a filesystem yet (vn_open() 
will die horribly otherwise).

My use of rootdev is (obviously) flawed.  AFAICT, either rootvp 
or rootvnode should be used, but I can't tell the difference between 
the two at a glance and am lacking development resources right now 
(my development box seems to enjoy dropping cores too frequently to 
build a kernel at the moment).

If somebody could test that rootvnode or rootvp are non-NULL after 
an NFS-mounted root is set up, I'd thankfully approve the quick 
fix... :*)

Cheers.
