i have kubuntu installed on 1 partition (and a swap obviously) ideally i would prefer it if /home was on a separate partition, can i achieve this without starting OS installation again ?
Is the hardrive full or do you have unpartitioned space? If it is full, resizing partitions can be dangerous for your data.

For instance, if you're using Ext3 and your drive has some extra space (and not too many bad sectors), take a look over here: Resizing ext3 partitions with parted | Uwe Hermann ...That said, it's best to do it before you get everything setup, not after the installation.
