All,
It seems like I am running out of disk space on my home partition. I installed through Wubi in Windows, and thought that 10GB would be enough. I've attached a link to a screenshot hoping it would aid the situation:

I tried expanding the /host/ubuntu/disks/boot device using gparted, but that did nothing to improve /host/ubuntu/disks/root.disk. Where should I be doing that? Aren't they the same device?
