bug#23697: guix system reconfigure hangs, shows repl in messages

[Jan Nieuwenhuizen]

Hi,

Not sure this qualifies as a bug, sending per request.

As a preparation to move from Debian to GuixSD, I have been dual
booting between Debian and GuixSD.

Using Debian as my main system with this layout

    /dev/sda3 "debian" /
    /dev/sda1          /guix
    /dev/sda4          /home

I did

    guix system init drakenvlieg.scm /guix

see attached, and then booted into GuixSD.  GuixSD still using its own
/home on its sda1 root.

On GuixSD, I ran Gnome and mounted the home I had been using with Debian

    /dev/sda1 "guix"   /
    /dev/sda3 "debian" /debian
    /dev/sda4          /hoom    <--manual mount

I set $HOME /to /hoom/janneke and checked that some things like wifi,
fonts, ssh, gnus, openvpn, touchpad etc. worked good enough to switch
over.

Then, I uncommented the /home section in drakenvlieg.scm, like so

    ;; Switch to GuixSD
    (file-system (device "home")
                 (title 'label)
                 (mount-point "/home")
                 (type "ext4"))
    (file-system (device (label "Debian")) (title 'label) (mount-point 
"/debian") (type "ext4") (flags '(read-only)))

and (without considering I had mounted /hoom and set $HOME there) ran

    guix system reconfigure drakenvlieg.scm

which eventually printed

    ...
    guix system: loading new services: file-system-/home urandom-seed ntpd 
avahi-daemon ssh-daemon...
    shepherd: Evaluating user expression (register-services (primitive-load 
"/gn...") ...).

In /var/log/messages I found some clue as to why this did not return

PS: I booted into Debian, did a new system init into /guix and am
    running GuixSD now.
