Re: Getting Guix to shutdown my laptop properly with Sway and no DE

["Ignas Lapėnas" <ignas@lapenas.dev>]

Hello,

I have the same (or extremely similiar) issue. It seems that it is because of
shepherd. The system seems to work alright, although can’t communicate with it
at all. For some reason it hangs. Tried looking for logs for the program, sadly
I’m extremely new to Gnu Guix and still stuck here. :(

(Writing this out with an idea that it might maybe help)
