Hi!

plase is there someone else that could reproduce this issue with "guix
system container": https://issues.guix.info/issue/34211 ?

I'm still not able to run a container built using "guix system container
container-minimal.scm -r container-minimal"

I'm on guix commit: 4aeb7f34c948f32363f2ae29c6942c6328df758c

this is the simple container.scm I'm using:

I also get this behavior.

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

The container is working as expected though.  If you find the PID of the
container’s ‘shepherd’ process (its PID 1, which obviously has a
different PID outside the container), then you can do:

  guix container exec NNN /bin/sh

where NNN is that PID of that ‘shepherd’ process (I use ‘pstree’ to find
the PID… not very convenient.)

In that shell, you can do:

--8<---------------cut here---------------start------------->8---
sh-4.4#  . /etc/profile         
sh-4.4# ls
bin  dev  etc  gnu  home  proc  root  run  sys  tmp  var
sh-4.4# herd status
Started:
 + containerized-shepherd
 + file-systems
 + guix-daemon
 + host-name
 + loopback
 + nscd
 + root
 + root-file-system
 + ssh-daemon
 + syslogd
 + term-tty1
 + term-tty2
 + term-tty3
 + term-tty4
 + term-tty5
 + term-tty6
 + udev
 + urandom-seed
 + user-file-systems
 + user-processes
 + virtual-terminal
Stopped:
 - console-font-tty1
 - console-font-tty2
 - console-font-tty3
 - console-font-tty4
 - console-font-tty5
 - console-font-tty6
 - networking
 - term-auto
 - user-homes
--8<---------------cut here---------------end--------------->8---

So in that sense everything is working “as expected.”

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

Thoughts?

Thanks,
Ludo’.

Hi Ludo'

thank you for looking into this issue!

OK, so this is deterministic now :-)

actually they do fail but they are not respawned, the services that get
respawned are term-tty[1..6]

I have to use "sudo" to be able to start and "guix container exec" a
shell in it (I mean: sudo guix container exec...)

I used that command in another terminal so I could see the console
messages from the container

> where NNN is that PID of that ‘shepherd’ process (I use ‘pstree’ to find

oh yes! I did not realized that my container was there waiting for me
:-)
...I also did not realized thet the container is started as a foreground
process, so we nees to background

I used pstree too, we need a better way to interact with a container (by
name and not by PID); sorry but I still cannot help here, my Guile
proficency is still too low; anyway this is tangent to this bug

yes, I see: I stopped term-tty[1..6] and the failure messages disappeared

as pointed above the faining services are term-tty[1..6],
console-font-tty[1..6] fails but do not get respawned do they are not
the real issue

> Not sure if we should do that automatically.

I'll try to remove term-tty[1..6] manually from services declaration, if
I manage to "manually" solve this I'll report here

> Thoughts?

since mingetty does not make sense in a container I'd remove
term-tty[1..6] (and console-font-tty[1..6]) automatically and by default
when we create a container via "guix system container..."

Thanks!
Giovanni

I tried but failed, I'm removing both mingetty and console-font from
%base-services list:

--8<---------------cut here---------------start------------->8---
  (services (cons* (service dhcp-client-service-type)
		   (service openssh-service-type
                            (openssh-configuration

                             (permit-root-login 'without-password)
                             (authorized-keys
                              `(("gbiscuolo" ,(local-file "ssh-authorized-keys/gbiscuolo.pub"))))
                             (port-number 22)))
		   (remove (lambda (service)
			     (eq? (service-kind service) mingetty-service-type)
			     (eq? (service-kind service) console-font-service-type))
			   %base-services))))
--8<---------------cut here---------------end--------------->8---

but term-tty[1..6] and console-font-tty[1..6] processes still get
installed and started by herd

please any hint on how to "manually" remove those two failing services?

Thanks!
Giovanni
