Yes. Here's a relevant TODO:

> Docker containerizer will leak dangling symlinks if restarted with a colon in

> Key: MESOS-7450
> URL: https://issues.apache.org/jira/browse/MESOS-7450
> Project: Mesos
> Issue Type: Bug
> Components: containerization, docker
> Affects Versions: 0.21.0, 1.2.0
> Reporter: Joseph Wu
> Priority: Major
> Labels: mesosphere
>
> The Docker CLI has a limitation, which was worked around in MESOS-1833.
> TL;DR: If you launch a container with a colon ({{:}}) in the sandbox path, we
> will create a symlink to that path and mount that symlink into the Docker
> container.
> However, when you restart the Mesos agent after launching a container like
> the above, the Docker containerizer will "forget" about the symlink and
> thereby not clean it up when the container exits. We will still GC the
> actual sandbox, but not the symlink.
