#!/bin/sh
# install1.fs disk 'install'
# Simplified, interactive NetBSD installation script.
# D.E. Silvia (dsilvia@net.com)
#
# (once again hacked on by rgrimes 1993/07/29,
#  disabled old disktab.preinstall,
#  added questions for what blocking factor to use in the file system,
#  added (heads) to clarify what disk tracks means)
#
# (heavily hacked by cgd)
# (and again by rwgrimes, for bad144 support and some error checking)
#
# Provides for variable swap and multiple partitions.
#
# Installs first minimal part of basic NetBSD system.
#
# Does not appear to work properly IF not using whole disk _AND_ there is
# no DOS partition (kernel bug?  Tries to chroot to partition 'd' :-{ )
#
# Currently, no method for checking to see if the designated disk type is
# already in /etc/disktab.  You can edit it out of the file after installation.
