Hello,
At a remote location, I have two boxes that are connected with each
other via a serial cable, and through a router to the internet.
One of the boxes is OpenBSD 3.6, and I'd like to upgrade it to 3.8,
and then compile -current (I want to play with the kernel alongside
sensors.h / lm(4)).
What's the best way to do it?
I guess, wget'ing the bsd.rd from ftp.openbsd.org mirror would be the
best "installation media", but then upon reboot should I choose
'upgrade' and do 3.6 -> 3.7, then repeat the procedure with 3.7 ->
3.8, then cvsup and compile the -current from sources? Or should I
'install' 3.8, then cvsup -current, and compile?
If I'll choose to install 3.8, then will I be able to leave my
partitioning scheme and contents of my custom partitions intact? Or
will I have to repartition the drive?

P.S. Is the upgrade really that simple and straightforward on OpenBSD
as it seems to be? :-)
P.P.S. BTW, as you can see I have some free disc space left... Is it
possible to install two versions of OpenBSD on separate slices of one
HDD and multiboot them? Or better and simpler just do the upgrade? :-)
Thanks,
Constantine.
