Re: [PATCH] Support to change set file via arg

(Removing HTML formatting on email thread so it doesn't get blocked).

For ChromeOS, we're working towards having a single build/image based
on a reference board that then supports multiple models created by
OEMs.

Some of the bluetooth config differs on a per model basis, so we need
to have multiple *.conf files ship on the actual image.

We then modify the init script to check the model at runtime and pass
the appropriate *.conf file to bluetoothd when it is started.

Currently, there is an expectation of the main.conf file at a specific
location.  This prevents system builds that support more than one
platform.

This adds support so the main.conf file can be specified as a command
line arg instead, so systems can manage multiple conf files as necessar=

and pass the appropriate conf file when the daemon is started.

I am failing to understand why this is needed. What problem are you tryi=

Btw, can't you link the main.conf with the board specific config?
Still it would be good to know what is that needs changing, is this
related to ControllerMode?
