I stopped my little experiment with Debian for now... I'll be back. Someone on reddit politely suggested I try to install Debian in a smaller partition. I think I'll do that, my PC has 2 SSDs, and one has plenty of space for such a slice.
Reinstalled a backup of Ubuntu Studio onto the main SSD.
That's a shot of Nico Kailani from Collective Central in Open Sim, at the Friends hypergrid. She was wonderful to converse with. Say hi if you ever see her there, or in Second Life.
