Review request for mesos, Chi Zhang, Dominic Hamon, Jay Buffington, Jie Yu, and
James Peach.
Bugs: MESOS-2350
https://issues.apache.org/jira/browse/MESOS-2350
Repository: mesos
Description
-------
Optionally take a path that the launch helper should chroot to before exec'ing
the executor. It is assumed that the work directory is mounted to the
appropriate location under the chroot. In particular, the path to the executor
must be relative to the chroot.
Configuration that should be private to the chroot is done during the launch,
e.g. mounting proc and statically configuring basic devices. It is assumed that
other configuration, e.g., preparing the image, mounting in volumes or
persistent resources, is done by the caller.
Mounts can be made to the chroot (e.g., updating the volumes or persistent
resources) and they will propagate in to the container but mounts made inside
the container will not propagate out to the host.
It currently assumes that at least {{chroot}}/tmp is writeable and that mount
points {{chroot}}/{tmp,dev,proc,sys} exist in the chroot.
This is specific to Linux.

Testing
-------
Manual testing only so far. This is harder to automate because we need a
self-contained chroot to execute something in... Suggestions welcome.
Thanks,
Ian Downes
