> Currently there is no standard way in Mesos to launch a child process in a different
namespace (e.g. {{net}}, {{mnt}}). A user may leverage {{Subprocess}} and provide its own
{{clone}} callback, but this approach is error-prone.
> One possible solution is to implement a {{Subprocess}}' child hook. In [MESOS-5070|https://issues.apache.org/jira/browse/MESOS-5070],
we have introduced a child hook framework in subprocess and implemented three child hooks
{{CHDIR}}, {{SETSID}} and {{SUPERVISOR}}. We suggest to introduce another child hook {{SETNS}}
so that other components (e.g., health check) can call it to enter the namespaces of a specific
process.
