Tonight I finally got around to upgrading my OpenBSD machine, Vectra functions as my file server among other things hehe. The 4.2 upgrade screwed around with the expat library making it depend on xbase42.tgz which is the X Windows System, normally not needed unless one is running a graphical desktop environment.
The system runs headless with no monitor, keyboard, or mouse and functions as a file server. So I have no need what so ever to run a GUI, using a command prompt over SSH is actually my preferred way of working on the box any way. because it means I don’t need a monitor, keyboard, or mouse to work on Vectra and because SSH is not as heavy on the network as using VNC/X Forwarding and crap. Now that 4.3 was released May 1st and fixed the libexpat thing I can update
I took the machine from OpenBSD 4.1 to 4.2 to 4.3. I could probably have saved time by not dealing with any of the *42.tgz files besides etc42.tgz but I did it any way. I’ve also learned the hardway to back up /root first hehe (see end of post notes). OpenBSD is one of the most easy to install, upgrade, use, and maintain operating systems I have ever used.
Here is my general log of things, and yes I do use the shells command grouping and flow-control constructs when I feel like it :-P. Most of the configuration file changes in 4.2/4.3 were never modified by me so I could install most of them over the old ones
EDIT:, be sure to remove BOTH etc*.tgz before using any the for loops to install files!!! or end up in my sleepy boat. Updating the files in /dev before rebooting is also not a bad idea.

Since there are a lot of printing related packages from back when I screwed with setting up a Lexmark WinJet with cups awhile back and the Samba system which is no longer used… Since oddly integrating Windows and BSD clients forced me into NFS shares : I’ve opted to delete all of the packages installed on the server and reinstall the only ones I actually give a flying rats rear end about
pkg_delete -cxi -F dependencies /var/db/pkg/*
pkg_add -vi bzip2 lzma
Sadly it seems that /root/profile for some odd reason was overwritten by one of the upgrade files, which really sucks… Because I didn’t stop to think — the tarballs for upgrade are the same as a fresh install which has to create roots default home directory!!!
I had set up roots ~/.profile to set PKG_PATH dynamically based on the current architecture and release level. So I redirected the output of ‘set’ to a file to retain the values and rewrote my file by hand and changed ~/.profile to source a separate ~/.kshrc before rebooting the system
set > /tmp/root.profile
vim -o ~/.profile -o ~/.kshrc
shutdown -r now
