problem with dockerd service

Hi!

I'm trying to create a VM with a dockerd service installed

I'm using the same configuration as the one used in this bug #34333
http://issues.guix.info/issue/34333
except I removed gfs package gnome and desktop services

I get this error:
--8<---------------cut here---------------start------------->8---
$ guix system vm ../labs/configuration/docker-test.scm -r docker-test
guix system: error: service 'dockerd' requires 'file-system-/sys/fs/cgroup/blkio', which is not provided by any service
--8<---------------cut here---------------end--------------->8---

it this related to bug #34333 or it's a different issue?

Thanks!
Giovanni

It's a different issue.

docker requires elogind.

I wonder why it doesn't complain about 'elogind' missing, though.

Please add elogind to your service definition.

If it's already there, that's weird, because elogind provides %control-groups,
which includes 'file-system-/sys/fs/cgroup/blkio'.

ah OK, I missed this!

would it be possible to "autoinstall" elogind service when using docker
in a service declaration?

in general: is it possible to "autoinstall" services dependencies?

it works! "guix system container..." and "guix system vm..." now both
completed the derivation

Thanks a lot!
Giovanni
