To add more info, the issue reoccurs every time a new update is downloaded via guix pull. Then I reconfigure and the command hangs forever at "guix system: bootloader successfully installed on (/dev/sda)". The only way to shutdown my laptop after this is by pressing the power button, loginctl poweroff and sudo poweroff hangs forever and do nothing. Then I turn my laptop on, log in, run guix pull && sudo guix system reconfigure config.scm and if no update is available, this time the command succeeds.
