Greetings and Salutations, A few days ago, I asked for help in making a step by step list on how to "copy" OpenBSD from one computer to another. Well I got a few answers, but many people wanted me to post this list when I was done. So this is it, a mindless checklist of everything I did to "convert a DEC 3100 to the Dark Side" If you can think of something I have missed, please throw me an e-mail. Thanks Daniel Colpi colpi@purdue.edu ====================================================================== So, you want another OpenBSD computer hu? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ (assuming same disk setup, target is disk #0, and source is disk #1) (also assuming rrz0a -> / ; rrz0c -> swap rrz0d -> /usr ; rrz0e ->/usr/target ) (Note: I am on a /bio backbone, this isn't going to be the same for you) (Note: /bio/scratch3 is a temp space that I can write to) ___Save Files ___dump root to scratch (just in case) -->% dump -0f /bio/scratch3/dump /dev/rrz0a ___/etc/passwd --> % mv /etc/passwd /bio/scratch3/passwd.target ___/etc/crontab ___any self created scripts you made to run with crontab ___/etc/fstab ___/usr/local/etc/mk-exports ___/etc/export.hosts ___/etc/export.fs.[n] (if you have a drive that is set up the way you want for target machine, you might want to save it to a file to save you some time) (Note: you might want to do this on a machine that is already converted) ___save your partition list -->% disklabel -r /dev/rrz1a >> temp_part % mv temp_part /bio/scratch3 ___Shut down target ___Connect source drive ___Make sure drives are jumpered not to conflict (target=>0 ; source=>1) ___Plug in and power up ___Make sure clock is right time (some old computers lose some time) ___Make sure you see both drives (ie drive 1 & drive 0) ___Run disklabel (I had drouble labeling the disk, but this worked) -->% disklabel -r /dev/rrz1a >> temp % disklabel -B -R /dev/rrz0a temp % disklabel -e /dev/rrz0a ___ / = _______________ ___ swap = ____________ ___ /usr = ____________ / ______________ (target / source) (remove src if desired) ___ /usr/target = _______________ (if you have a "cookie-cut" version you can just:) -->% disklabel -B -R /dev/rrz0a /bio/scratch3/temp_part ___Run newfs -->% newfs /dev/rrz0[ad] ___Transfer files --->% mount /dev/rz0a /mnt % cd /mnt % df -k .
