Partitioning was done manually and based on unclear thoughts as well as unconfirmed facts gathered on the net. This is how I chose to do it:
/boot 100 MB ext2
/tmp 5 GB ext2
(someone, somewhere once wrote that it was a good idea to keep boot and tmp separate in ext2 since for some reason journalling would be bad. Don’t know really, please enlighten me if you can).
/ 60 GB JFS
/home 200 GB JFS
(someone, somewhere once wrote that JFS was faster than Reiser which I have been using previously. Feels kinda awkward to use Reiser these days anyways, look for Hans Reiser in Wikipedia if you don’t know about it..)
I also kept around 50 GB that I might end up using as a raw disk for Windows in Virtualbox.
