Maybe something like this?
rump_allserver -d key=/dev/partition,hostpath=NetBSD-7.99.1-amd64-live-wd0root.img,disklabel=a unix://sock
RUMP_SERVER=unix://sock LD_PRELOAD=/usr/lib/librumphijack.so installboot -e -o console=com0 /rump/dev/partition
RUMP_SERVER=unix://sock rump.halt
May have to mess with the pathnames -- I always forget the rules for
how they get translated. There's a slightly cheaper rump_server
incantation with an appropriate selection of modules, maybe just
-lrumpdev, but I don't remember what it has to be offhand.
