I also get this behavior.

What happens is that the /dev/ttyN nodes do not exist (understandably),
and thus the =E2=80=98console-font-ttyN=E2=80=99 Shepherd services fail to =
start, and
get restarted, indefinitely.

The container is working as expected though.  If you find the PID of the
container=E2=80=99s =E2=80=98shepherd=E2=80=99 process (its PID 1, which ob=
viously has a
different PID outside the container), then you can do:

  guix container exec NNN /bin/sh

where NNN is that PID of that =E2=80=98shepherd=E2=80=99 process (I use =E2=
=80=98pstree=E2=80=99 to find
the PID=E2=80=A6 not very convenient.)

In that shell, you can do:

--8<---------------cut here---------------start------------->8---
sh-4.4#  . /etc/profile=20=20=20=20=20=20=20=20=20
sh-4.4# ls
bin  dev  etc  gnu  home  proc  root  run  sys  tmp  var
sh-4.4# herd status

 - user-homes
--8<---------------cut here---------------end--------------->8---

So in that sense everything is working =E2=80=9Cas expected.=E2=80=9D

Now, it would make more sense to simply remove those =E2=80=98console-font-=
ttyN=E2=80=99
services in a container and everything that depends on them.  Not sure
if we should do that automatically.

Thoughts?

Thanks,
Ludo=E2=80=99.
