Upgrading OpenBSD

[Jukka Virtanen <jtv_(_at_)_cc_(_dot_)_hut_(_dot_)_fi>]

	Hi...

	I wrote a little shell script that upgrades OpenBSD from the
	snapshots with a few extras compared to a plain tar unpack :-)

	Theo said he would like to put it in genaral use, but that it
	would be useful to get some comments and more importantly:
	test it in some other platforms besides i386.

	If you are interested in testing it and/or giving
	me comments to improve it, please send me mail.

	The sample output of the script is attached to
	the end of this mail: this run upgraded my
	Ultra-2000 laptop from 20.Oct.1998 snapshot to
	22.Oct.1998 snapshot (the latest snapshot I found).

					jtv_(_at_)_hut_(_dot_)_fi

	ps. If someone has PMAX snapshots, I have an 
	old decstation 5000/133 running OpenBSD 2.2 here, so I can
	check that.

=== cleaned up typescript of the sample run, upgrading my laptop:

zoo (15:36) /usr/upgrade-22.10# UPGRADE.OpenBSD -b /update/OpenBSD/snapshots/22.10.98/i386

      This program will verify and install OpenBSD-24 snapshots.

PLEASE NOTE: You should check the contents of the save file:
/usr/upgrade-22.10/upgrade-saved-6304.tar.gz
It is a compressed tar file of the old system files saved during installation.
(This save file has been extracted to: /usr/upgrade-22.10/NEW-FILES.6304).


Some files have already been restored from your old system.
New versions of these files have been saved before replacing them.
