> when using karaf in clouds & PaaS infrastructures like OpenShift, Docker, OpenStack et al; its common to use environment variables to pass in environment specific values; then keep a single disk image. It would be nice if there was an easy way to reference environment variables similar to the ${foo.bar} syntax for accessing system properties.
> Maybe karaf should support some kind of environment variable expansion like
> {code}
> # define a property based on an env var
> foo = ${ENV.nameOfEnvVar}
> # e.g. here's the host name
> host = ${ENV.HOSTNAME}
> {code}
