Debian 11.0 (bullseye)
There's a new Debian to upgrade to as of today. I will be doing this as soon as I convince myself it won't be causing anything to die horribly, and then finish a round of backups. Probably tonight or tomorrow sometime.
Update (Sunday, 10:19pm PDT): The downside of staying up for 300+ days straight is that everything has to fsck now. Hopefully this will go well, but it may take a while.
Update (Sunday, 10:49pm PDT): libcrypt.so.1: cannot open shared object file: No such file or directory (and before you ask, yes, the package libcrypt is installed, so it looks like I get to go hunting through Changelogs to see WTF happened. This is going to take way, way longer.
Update (Monday, 11:30pm PDT): The good news is I've successfully created an environment on my Debian 11 virtual machine that can run the moo server executable. There remains the small matter of deploying to my actual machine and not getting bitten by further surprises. If all goes well we'll be back on the air sometime tomorrow. Longer term, there's stuff to talk about (I'll go into detail on *Server, but the tl;dr is we're going to want to be a 64-bit MOO by the time Debian 12 comes out...)
Update (Tuesday, 11:15pm PDT): And we are back up. Yay. (Thanks to Ken Fox and the other folks at Waterpoint for saving me a lot of time...)
