[pkg-go] Bug#806261: docker-registry: Cannot access config.yml

[Olaf Meeuwissen]

Package: docker-registry
Version: 2.1.1~ds1-4
Severity: important

Dear Maintainer,

I just installed docker-registry and noticed it didn't start up during
installation.  A look at /var/log/docker-registry.log said:

  configuration error: open /etc/docker/registry/config.yml: permission denied

I tracked this down to a permission issue on /etc/docker/:

  $ ls -dl /etc/docker
  drwx------ 3 root root 4096 Nov 26 08:15 /etc/docker

The init script checks whether it is being run as root so that isn't the
problem but then tries to run `start-stop-daemon --chuid "$EXECUSER"`
with EXECUSER=docker-registry.  This means that the BINARY cannot access
its own configuration file.  Oops.

A subsequent attempt to purge the package failed because docker-registry
could not be stopped.  Obvious, because it isn't running in the first
place.  Perhaps you should add a check that it is indeed running before
exiting with a failure when you cannot stop it because it isn't running.
