6# Builds all the bat-shit crazy combinations we support booting from,
7# at least for amd64. It assume you have a ~sane kernel in /boot/kernel
8# and copies that into the ~150MB root images we create (we create the du
9# size of the kernel + 20MB
10#
11# Sad panda sez: this runs as root, but could be userland if someone
12# creates userland geli and zfs tools.
13#
14# This assumes an external prograam install-boot.sh which will install
15# the appropriate boot files in the appropriate locations.
16#
17# These images assume ada0 will be the root image. We should likely
18# use labels, but we don't.
19#
20# ASsumes you've already rebuilt... maybe bad? Also maybe bad: the env
21# vars should likely be conditionally set to allow better automation.
