Just for kicks, I built a kernel with my standard config but UVM disabled.
And, sic!, in single user I could disklabel(8), mount and unmount the MO
just fine, even copy stuff to it (it has an LFS). Going to multi user would
crash the machine in flames, though.

(Is an UVM userland supposed to work with a Mach VM kernel? Is it supposed
to panic the kernel? Stack traces upon request.)
