---------------------------------

[~klueska] For mesos-local, should we change the default value of it?

> We recently introduced a new agent flag for {{--runtime_dir}}. Unlike the {{--work_dir}}, this directory is designed to hold the state of a running agent between subsequent agent-restarts (but not across host reboots).
> By default, this flag is set to {{/var/run/mesos}} since this is a {{tempfs}} on linux that gets automatically cleaned up on reboot. However, on most systems {{/var/run/mesos}} is only writable by root, causing problems when launching an agent as non-root and not pointing {{--runtime_dir}} to a different location.
> We need to call this out in the upgrade.md and getting-started.md docs so that people know they may need to set this going forward.
