@prabhjyotsingh I don't know how to support different users' environments
fully, actually. But I think it's better to use `RUNAS ~` and `su - ~` and
using `ssh` without password make some security issues. In case Mesos, it uses
that way to support restrict resources. But I never see using `ssh` without
password. How do you think of it?
