I changed it to look like:
PACKAGES += "${PN}-service"
FILES_${PN} = "${datadir}/*"
FILES_${PN}-service = "${systemd_system_unitdir}/canstart.service"
do_install () {
if test -e ${WORKDIR}/can_start.sh &&
test -e ${WORKDIR}/canstart.service; then
install -d ${D}${datadir}/canstart
install -m 0755 ${WORKDIR}/can_start.sh ${D}${datadir}/canstart
install -d ${D}${systemd_system_unitdir}
install -m 0644 ${WORKDIR}/canstart.service
${D}${systemd_system_unitdir}
sed -i -e 's|@SCRIPTDIR@|${datadir}/canstart|g'
${D}${systemd_system_unitdir}/canstart.service
fi
}
SYSTEMD_PACKAGES = "${PN}-service"
SYSTEMD_SERVICE_${PN}-service = "canstart.service"
SYSTEMD_AUTO_ENABLE_${PN}-service = "enable"
Still got the same results, my task is not running at startup.
To make sure that there wasn't some problem in running the script, I changed
the ExecStart to echo to a file in /tmp. Nothing there. The .service file is
not being executed.
I've obviously got something totally messed up, but I'm darned if I understand
what it is.

Subject: Re: [yocto] trouble getting systemd oneshot to run
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,

I'm running into two problems, I've got all of the files copying to the correct
locations but the .service is not running at startup. I used
connman-conf.bb<http://connman-conf.bb> as the template for my .bb file:
SUMMARY="recipe to create CAN bus startup service"
LICENSE = "CLOSED"
LIC_FILES_CHKSUM = ""
inherit systemd
SRC_URI = "file://can_start.sh \
file://canstart.service \
"
S = "${WORKDIR}"
PACKAGE_ARCH = "${MACHINE_ARCH}"
FILES_${PN} = "${datadir}/*"
do_install () {
if test -e ${WORKDIR}/can_start.sh &&
test -e ${WORKDIR}/canstart.service; then
install -d ${D}${datadir}/canstart
install -m 0755 ${WORKDIR}/can_start.sh ${D}${datadir}/canstart
install -d ${D}${systemd_system_unitdir}
install -m 0644 ${WORKDIR}/canstart.service
${D}${systemd_system_unitdir}
sed -i -e 's|@SCRIPTDIR@|${datadir}/canstart|g'
${D}${systemd_system_unitdir}/canstart.service
fi
}
SYSTEMD_SERVICE_${PN} = "canstart.service"
Service file:
[Unit]
Description=Startup CAN bus interface
[Service]
Type=oneshot
ExecStart=@SCRIPTDIR@/can_start.sh
[Install]
WantedBy=network.target

The second 'problem' is really just perplexing, if I dump the variables S
contains a path to a directory in my root not "${WORKDIR}".
Any and all help with this would be greatly appreciated.
