After a guix pull on 0fc235a, guix system reconfigure stop at

--8<---------------cut here---------------start------------->8---
shepherd: Evaluating user expression (let* ((services (map primitive-load (?))) # ?) ?).
--8<---------------cut here---------------end--------------->8---

instead of

--8<---------------cut here---------------start------------->8---
shepherd: Evaluating user expression (let* ((services (map primitive-load (?))) # ?) ?).
shepherd: Service user-homes has been started.
shepherd: Service term-auto could not be started.
bootloader successfully installed on '/dev/sda’
--8<---------------cut here---------------end--------------->8---

The only change I've done to my config.scm is that now I have a btrfs
filesystem (just for storage, it's not /home).

The “Evaluating user expression” started the ‘file-system’ service for
this btrfs file system, and it got stuck for some reason.  Did
/var/log/messages or the console show anything?

I suppose you’d have to try again the experiment.  Presumably there’s
some fsck-like process or something taking time or waiting for input.

This is the last message in /var/log/messages:

--8<---------------cut here---------------start------------->8---
Aug 29 09:13:40 localhost shepherd[1]: Evaluating user expression (let* ((services (map primitive-load (?))) # ?) ?). 
--8<---------------cut here---------------end--------------->8---

What console?

Note that everything works alright.  But I'm worried that this would
fail on a new installation where the bootloader is missing :(

/dev/console, so tty1, typically.

Where the bootloader is missing?  The bootloader cannot be missing or
the thing is not installed.  :-)

No it's not missing, but I think the bootloader remained from the
previous working configs (before I configured the Btrfs file system).

Say I'd wipe the bootloader now and re-run `guix system reconfigure...',
I don't think it would get installed then.

Had you considered the case where someone[1] is running a binary install
on a foreign distro booted by refind or a bootloader not in your official list?

[1] guess who ;-)

I hadn’t!  If that’s the case, it’ll be more difficult for us to support
that someone.  :-)

Just checked: no messages in the /dev/tty1.
Isn't there a more extensive log for "guix system reconfigure"?
Something seems to be wrong with btrfs.

You could look at the .scm files produced by "guix system reconfigure"
(the store paths should be printed to stdout). I'm afraid that, aside
from Shepherd's own messages, the console output is the canonical log
for "guix system reconfigure" right now.

Jakob

With today's guix commit 

4cd9de6068f439c52f6874f00ec608c41156d095

guix system reconfigure worked flawlessly with the same config.scm.
