		About /etc/hosts on the miniroot

The file /etc/hosts needs to be writable, so it is a symbolic link to
/tmp/hosts.  When /tmp is mounted on a writable file system,
/etc/hosts.base is copied into /tmp/hosts.  Until then, /tmp/hosts is a
symbolic link to /etc/hosts.base so that everything appears normal.


			About this directory

This directory contains files used in building an installation
diskette.  This diskette is required in order to install IBM
Academic Operating System 4.3 on the IBM RT PC workstation.

In order to make an installation diskette, you first need to make
a miniroot kernel and other binary files with the command:

	1> cd /sys/dist; make MINIROOT

To create the diskette itself, use the command:

	2> cd /sys/dist; make diskette

To use the local /etc/hosts hosttable, use the command:

	2> cd /sys/dist; make diskette LOCAL=-local

The sed script mkMINIROOT converts the generic kernel configuration
file into the configuration file for the miniroot kernel.

The shell script restore.tape is the installation command, and
restore.net is a hard link to it on the installation diskette.

The directories bin, etc, and usr/ucb contain installation versions
of some of the utilities used in the system installation process.

The shell script make.minimal installs an image of a clean minimal
file system on a master machine for use with reduced and minimal
installations.

The shell script make.site removes directories located (by default)
in /andrew/usr that need to be written to regularly.  It then
replaces them with symbolic links to /site.  This is needed so
minimal and reduced systems can write to directories like /usr/spool,
/usr/adm, /usr/tmp, etc.
