> Project: Mesos
> Issue Type: Improvement
> Reporter: Chun-Hung Hsiao
> Priority: Major
> Labels: integration
>
> Currently if a Mesos master/agent command-line flag is of type {{Option}},
> the only way to leave it as {{None}} is to unset the corresponding {{MESOS_}}
> environment variable and don't specify the flag. Although this works, it
> would be nice if the user could:
> 1. Override environment variable through command-line flags, e.g.
> {{--feature_flag=none}}.
> 2. Override environment variable with another value, e.g.,
> {{MESOS_FEATURE_FLAG=none}}. This is especially useful if users are managing
> Mesos through systemd and specifying flags through environment files.
