Repartitioning the disk
 

I have a Laptop with Linux instaled, and I need to make room for an OpenBSD instalation. This is my current hd status.
# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/hda2 487M 292M 195M 60% /
/dev/hda5 9,4G 2,9G 6,5G 31% /usr
/dev/hda6 957M 33M 925M 4% /tmp
/dev/hda7 957M 685M 273M 72% /var
/dev/hda8 26G 8,4G 17G 34% /home
/dev/hda1 16M 7,1M 7,4M 50% /boot

So I want to ask, what's the best way to do this?
Do I have to reinstall Linux, or can I resize a partition, /usr for example?
I know that OpenBSD has to be instaled within the first 8Gb, so my only option here is /usr.

TIA,

you will need to move some of your data around while you reformat/partition segments of your disk...

I advise doing this in single user mode with networking turned off.

next time, use the code tags to make your output a little easier to read...
