Review request for mesos, Gilbert Song, Jason Lai, Jie Yu, and Jiang Yan Xu.
Bugs: MESOS-9319
https://issues.apache.org/jira/browse/MESOS-9319
Repository: mesos
Description
-------
Previously, if the container was configured with a root filesytem,
the root was populated by a combination of the `fs::chroot:prepare`
API and the various isolators. The implementation details of some
isolators had leaked into the chroot code, which had a special case
for adding GPU devices.
This change moves all the responsibility for defining the
root filesystem from the `fs::chroot::prepare()` API to the
`filesystem/linux` isolator. The `filesystem/linux` isolator is
now the single place that captures how to mount the container
pseudo-filesystems as well as how to construct a proper `/dev`
directory.
Since the `linux/filesystem` isolator is now entirely responsible
for creating and mounting the container `/dev`, any other isolators
that enable access to devices should populate device nodes in the
container devices directory and add a corresponding bind mount.
