If you are in the need to set an environment variable for an smf service, you are looking for envvar. It get's set in the `service` scope or in the `exec_method` scope. Here is a small example, how it's used.

```
<exec_method type="method" name="start" exec="/bin/bash">
  <method_context>
    <method_environment>
      <envvar name="FOO" value="bar" />
    </method_environment>
  </method_context>
</exec_method>
```

This example sets the environment variable `FOO` to bar. This is espacially useful, when you have to modify `PATH` or `LD_LIBRARY_PATH`. Just don't forget, that you did it.
