I've updated the miniroot on Gregorio to one built from NetBSD-current
on November 30. (The kernel on the miniroot also has a small fix for
Ultrix compatibility that has since been merged in but weren't
suppable yesterday.)  This miniroot also has the correct special
device numbers for /dev/null et. al.

So far I don't think the kernel on the miniroot is quite as stable
as the older one; but it's there for those who want to try
more up-to-date kernels and can't build them themselves.
