Guix now boots to this screen[1] and then hard freezes. Just in case its relevant, I did the installation twice (both through TTY in order to run the mount/rm commands): 1. 2 partitions, boot and encrypted root w/ swapfile, using desktop.scm as a base 2. 3 partitions, boot, root, and a swap partition, using lightweight-desktop.scm as a base Both had the same results.
