Thanks Ian. Now that at $JOB we are no longer using NFS, and all
machines have /usr/src and /usr/obj populated (transferred from the
build machine), rebooting into single user mode after installing the new
kernel becomes much easier. I'll try this on further test 9.2-STABLE to
10.1-STABLE rollouts.
