[OpenWrt-Devel] [PATCH] procd: add daemon mode and remove pid 1 check

[Paul Spooren]

Add arg -D to start procd in daemon mode. This allows running procd
directly, not only via /init. Useful for CI environments to start
services like ubus and netifd without needing the whole init process.

To make this work procd also spawns services when running on a different
pid than 1, normal when started via terminal. Before it would only try
to connect to an existing ubus instance.

The -D arg handling was kindly created (with < 60 seconds RTT) by John,
I just created the patch and removed pid checking.
