[Buildroot] [PATCH v2 3/3] rpi-userland: Fix vcfiled startup

[Yann E. MORIN]

Benoit, All,

On 2014-08-06 15:39 +0200, Benoît Thébaudeau spake thusly:
> The VideoCore file server daemon startup script installed from this package is
> not compatible with BuildRoot (because of its naming and other Debian
> dependencies), which prevented vcfiled from starting. Hence, prevent this
> package from installing its vcfiled startup script, and install a vcfiled SysV
> init script suitable for BuildRoot.

I'm not sure I would be happy that the GPU is allowed uncontrolled
access to the filesystem.

Please, make this an option, defaulting to 'n', so the user can
willingly choose to install it or not.

Otherwise, see below...

Are you sure about the path to the PID file?
What about:
    PIDFILE="/var/run/$NAME.pid"

Othwerwise, looks good after a casual look. Ditto your previous patches,
I'll try to find some time tonight to test it.
