The manual install has a similar issue where in 2.1 Binary Installation
step 5, it asks you to run:

# cp ~root/.config/guix/current/lib/systemd/system/gnu-store.mount \
     ~root/.config/guix/current/lib/systemd/system/guix-daemon.service \
     /etc/systemd/system/

Which confused me during an install with the same "No such file" error
as above. I see that guix-install.sh now includes a conditional around
this `cp`. Perhaps it would be worth a small note in the documentation
to advise that this will issue a harmless error on Guix <= 1.1.1?
