This failed for both user and root.

config
====================
/var/guix/profiles/system-32-link/profile was installed by
'guix system reconfigure config.l.scm'
/var/guix/profiles/system-31-link/profile was installed by
'sudo ./pre-inst-env guix system reconfigure ../configs/config.k.scm'
config.l.scm and config.k.scm are identical.
gnug/packages/screen.scm contains a minor mod.
