I had forgotten that debian had switch ed version since my last update.
so, today, I'm moving from the old stable (sid, i think) to woody, which used to be testing. I had meant to leave this for a weekend long job.
Mid-upgrade, I realised that i had run out of disk space. I think i have things straightened out now, I hope.
Some stuff is still pretty broken, and the upgrade is still on going, but it has disk space to upgrade in, and the important sutff seems to be working.
