# this script should help to create base system images for use in FAI
# installations.
# even if debboostrap seems to have scripts for multiple different
# debian-based distributions, it most often does not succeed, for example to
# create etch base system from sarge, create debian base system from ubuntu,
# etc.
# in the end, you need the actual derbootstrap of this distribution.
#
# thsi script should help lazy people (so, at least myself :) ) to make it
# easy to create them anyway, also without installing and re-installing the
# currently needed deboostrap system.
#
# we have multiple possibilities:
# - download a ready made base system image for the
#   distribution wanted from a default location, or one given at the command
#   line
# - create a new base system  with 
#   - a debootstrap downloaded from the default location
#   - a debootstrap downloaded from a given location
#
# TODO: add the possibility to just download a readily created base image?
# TODO: add a script for centOS/redhat and other systems minimal image
# creation!
