adding a linux filesystem to openbsd

[Ognen Duzlevski <ognen_(_at_)_daocomputing_(_dot_)_com>]

Hi all,

I have been using OpenBSD for some time as my desktop machine at work 
(Gnome, Evolution, firefox). It is currently dual-booting with Ubuntu 
linux. Lately I am thinking of converting the Linux space into an 
OpenBSD filesystem and just keeping the OpenBSD install on the box (I 
really like what OpenBSD developers have been doing with the OS, its no 
frills simplicity and no clutter approach). However, my thinking is 
still a bit Linux-centric when it comes to administration. For example, 
in Linux I am comfortable firing up fdisk and changing things around. So 
far I am not as comfortable doing this in OpenBSD. Can anyone tell me 
the steps required to convert the Linux ext3 fs into an OpenBSD 
mountable partition that I can add to a filesystem such as e.g. /home? 
Or at least point to some reading material?

Thanks,
Ognen
