Disk Partion
 

Hi,
Is there a easy way to repartition your partitions after you have Linux installed or is it easier to just do a re-install?

Thanks,

It is easier to re-install. If this is something you think you'll have to do again in the future, you may consider using LVM next time you install.

If you mean you want to resize the partitions your Linux is using, then I agree with mostly with the previous poster but you can do a hybrid if you want to save your data without actually reinstalling and if you have another drive that's big enough.

Get rsync and copy your system to the other drive. (This can also be over a LAN to another box, rsync works great)
Repartition your main drive
make filesystems in the new partitions
rsync everything back
fix your bootloader and fstab as necessary
enjoy
