Jason Lai commented on MESOS-8257:
----------------------------------
After discussions with [~jieyu] on the refactoring done in {{launch.cpp}} for
platform-specific support, I decided to drop some of the patches till we reach
an consensus on how refactoring should be done for {{launch.cpp}}.
The new patch chain for this particular task has become:
* https://reviews.apache.org/r/65811
* https://reviews.apache.org/r/65812
* https://reviews.apache.org/r/65900
* https://reviews.apache.org/r/67175
* https://reviews.apache.org/r/67176
I'll add more patches for tests soon.
> Unified Containerizer "leaks" a target container mount path to the host FS
> when the target resolves to an absolute path

> Key: MESOS-8257
> URL: https://issues.apache.org/jira/browse/MESOS-8257
> Project: Mesos
> Issue Type: Bug
> Components: containerization
> Affects Versions: 1.3.1, 1.4.1, 1.5.0
> Reporter: Jason Lai
> Assignee: Jason Lai
> Priority: Critical
> Labels: bug, containerizer, mountpath
>
> If a target path under the root FS provisioned from an image resolves to an
> absolute path, it will not appear in the container root FS after
> {{pivot_root(2)}} is called.
> A typical example is that when the target path is under {{/var/run}} (e.g.
> {{/var/run/some-dir}}), which is usually a symlink to an absolute path of
> {{/run}} in Debian images, the target path will get resolved as and created
> at {{/run/some-dir}} in the host root FS, after the container root FS gets
> provisioned. The target path will get unmounted after {{pivot_root(2)}} as it
> is part of the old root (host FS).
> A workaround is to use {{/run}} instead of {{/var/run}}, but absolute
> symlinks need to be resolved within the scope of the container root FS path.
