# Multiple image builder script for flashdist
#
# (Assumes that you are installing stock flashdist /etc/rc, /etc/boot.conf
# and /etc/ttys files)
#
# To run this,
# 1. Unpack OpenBSD baseXX.tgz, etcXX.tgz and manXX.tgz to /tmp/openbsd
#    with tar p flag, and as root
# 2. You may want to adjust the flash geometry below to match your media size
# 3. Compile GENERIC, NET45xx, and GEODE kernels, and leave
#    them at the /usr/src/sys/arch/i386/compile/XXX/bsd locations, or adjust
#    the kernels used to what you actually need
# 4. Run this from the flashdist direcotry, ./flashimgbld.sh
