Package: docker.io
Version: 1.6.1+dfsg1-2
Severity: important
Dear Maintainer,
I recently upgraded from 1.3.3~dfsg1-2 to 1.6.1+dfsg1-2 and things
appeared to be fine. That is until I rebooted. When I try to run a
container I get
$ docker run -i -t --rm debian:jessie /bin/bash
FATA[0000] Error response from daemon: Cannot start container
c1f8cad6c54a7e914e21fa9371ef0d9675d7f511c3ee3bbfb2a8baf4d3aaf26d: [8] System
error: mountpoint for cgroup not found
Your changes to "fix" #783143 in 1.6.0+dfsg1-1 means that docker.io now
has a hard dependency on cgroupfs-mount or cgroups-lite. A Recommends:
no longer suffices.
Until the reboot things kept working because the cgroup mounts were all
mounted already.
Installing cgroupfs-mount fixed this for me without the need to reboot
or even restart docker.io.
I see there is a 1.6.2~dfsg1-1 in sid already but that still recommends
cgroupfs-mount or cgroup-lite.

I disagree, and think there may be some misunderstanding of what a
Recommends dependency means -- there are esoteric configurations
(including the no-longer-esoteric systemd case) where cgroupfs-mount
is not required to be installed at all. For example, users can manage
their cgroupfs hierarchy mounts themselves without that package ever
touching their system.
