# Script : sansinstaller
# Purpose: Install Slackware quick and dirty without the Slackware installer
#          For use for bootstrapping a new port when the installer isn't
#          yet available.
#          For best results, run this script on the same architecture as
#          the packages you've prepared (eg run this on an existing ARM box).
#          This is because many of the package's post install scripts run
#          ARM binaries, which obviously won't work if you run this script
#          on x86.

### Notes ####
# [1] This script needs to be put into the "slackware" directory
#     eg.  armedslack-12.2/slackware
#     As root user on which ever host you choose, run it from this directory.
#       cd armedslack-12.2/slackware
#       ./sansinstaller
# [2] READ this script and make the modifications you need.
# [3] This script is not supported.
