Hello, after pulling recent Guix, I got this error during guix deploy: --8<---------------cut here---------------start------------->8--- guix deploy: warning: an error occurred while upgrading services on '127.0.0.1': %exception #> --8<---------------cut here---------------end--------------->8--- After rebooting, the system got stack during startup. No error message was visible, it was just hanging. Booting to previous generation did work.
