Subject: [PATCH] tools: Enable start of FRR for non-root user
There might be use cases when this would make sense, for example
running FRR in a container as a designated user.

+This option allows you to run FRR as a non-root user. Use this option
+only when you know what you are doing since most of the daemons
+in FRR will not be able to run under a regular user. This option
+is useful for example when you run FRR in a container with a designated
