I was changing my karmic to lucid on all my resources and changed that "/usr/share/python-apt/templates/Ubuntu.info" file to reflect lucid as well.
I thought what the heck and did a 'sudo aptitude dist-upgrade', and got 87 MB of updated data along with that new kernel. It booted back up ok, but I know the tool-chain is not uploaded yet. I checked and all the files have been updated. as of 10 minutes ago.
While I was still under karmic I was keeping updated.
At any rate its holding steady. That's what backups are for. in case this blows up in my face.
