I did an upgrade, and it told me that I didn't have enough space on /usr so I rebooted and made more then it told me I need avalible. I rebooted again when though the install again and it got past that part. However when it got to installed xpilot it ran out of space on my /usr partition and just sat there for an hour.
We have made some changes in the space calculations algorithms, so that should improve things for future releases.
