Re: [Trisquel-users] how to upgrade to belenos from 6.0

[strypey]

I know this doesn't help you right now, but I strongly recommend have  
separate partitions for / (root - your OS) and /home (your user files). That  
way you can install a new OS without needing an external drive, although when  
you're making any major changes to your OS (including version upgrades), it's  
a good idea to back up anything really essential somehow anyway.

15-20GB is plenty for your / partition (unless you install a lot of games and  
other large programs). The rest of the drive can be /home.
