[yocto] trouble getting systemd oneshot to run

[Jeremy Thien]

I am no expert, but I have a similar recipe. It might be over complicated,
but I put the script in one package and the service in another something
like:

PACKAGES += "${PN}-service"
FILES_${PN} = "${datadir}/canstart/canstart.sh "
FILES_${PN}-service = "${systemd_unitdir}/system/canstart.service "
SYSTEMD_PACKAGES = ${PN}-service"
SYSTEMD_SERVICE_${PN}-service = canstart.service"
SYSTEMD_AUTO_ENABLE_${PN}-service = "enable"

Of course, this requires image to install both canstart and
canstart-service.

Hope this helps,
Jeremy Thien
