You could have been a little clearer, but the main communication problem is that I didn't know that was a problem that could exist so it was easy to not follow. After a few minutes of confused web searching, I found https://fedoramagazine.org/thunderbolt-how-to-use-keyboard-d... which appears to describe the problem and some solutions (that don't involve homed, not least because this article predates it). AIUI, the problem is that you have to log in so you can approve the keyboard; that might be a pain point with an encrypted root (albeit it looks solvable), but if it works with homed I struggle to believe that it wouldn't work with any other encrypted home setup. Mostly because that part of homed is mostly a thin wrapper of code and convention over existing stuff.
