gpsd re-write

gpsd re-write

[Michael Lippautz]

Hej,

As I am re-writing the gpsd package, a few questions did come up.

1) gpsd can deal with multiple different gps devices (being served as
different nodes). Is it sufficient to start gpsd with a control socket
and add recipe for gps devices that just add init script that are
executed after gpsd startup. These init scripts could add the device
over the control socket. I.e. a recipe gpsd-device-... could add the
/dev/ttyACM0 node, using the control socket.

2) Since gps devices can also be integrated into platforms (machines)
a second approach using RDEPENDS_${PN}_machine can be used to build a
machine specific package. This machine specific package could init the
device and also attach it using the socket.

Is it "ok" to create such machine specific packages, i.e.
gpsd-hardware-om-gta01 ? How about "device" specific recipes (should
they be done in an other way)?

Additionally I can also add an /etc/default/gps-hardware file that
uses update-alternative to add the device at program startup.

Are these approaches correct? Don't want to sit and write these if
they are rejected anyways ;)

regards,
Michael

Your approaches are a lot better than the current 'gpsd only starts if
it was built for your machine *AND* OE has a config for it'
