# Builds all the bat-shit crazy combinations we support booting from,
# at least for amd64. It assume you have a ~sane kernel in /boot/kernel
# and copies that into the ~150MB root images we create (we create the du
# size of the kernel + 20MB
#
# Sad panda sez: this runs as root, but could be userland if someone
# creates userland geli and zfs tools.
#
# This assumes an external program install-boot.sh which will install
# the appropriate boot files in the appropriate locations.
#
# These images assume ada0 will be the root image. We should likely
# use labels, but we don't.
#
# Assumes you've already rebuilt... maybe bad? Also maybe bad: the env
# vars should likely be conditionally set to allow better automation.
