Hi,
I have a device with rootfs mounted readonly and with an overlay on top of
it to do the factory reset.
There's A/B partitioning. So there is a duplicate set of partitions.
There's an OTA engine to deploy atomics images.
I have the following usecase:
1. I flash a minimal image
2. I write the device type into a file (mutiple variant but same HW setup)
to a persistent data partition.
3. I deploy the common product image via OTA engine. The whole rootfs is
deployed atomically
4. I copy the current overlay partition content to the next overlay
partition
5. Reboot
6. System boots to the next slot to the common product image
Currently, the common product image is the minimal image with the addition
of this test-deployment package:
DISCRIPTION = "Test product specific deployment"
LICENSE = "CLOSED"
FILESEXTRAPATHS_prepend := "${THISDIR}/files:"
SRC_URI = " \
file://config.type1 \
file://config.type2 \
file://config.type3 \
"
do_configure[noexec] = "1"
do_compile[noexec] = "1"
do_install() {
install -d ${D}/opt/test
install -m 0644 ${WORKDIR}/config.type1 ${D}/opt/test
install -m 0644 ${WORKDIR}/config.type2 ${D}/opt/test
install -m 0644 ${WORKDIR}/config.type3 ${D}/opt/test
}
pkg_postinst_ontarget_${PN}() {
systemid=$(cat /persistent/systemid)
cd /opt/test
mv config.$systemid config
rm config.*
}
FILES_${PN} += " \
/opt/test/* \
"
The /opt/test folder is now present but it still contains config.type1,
config.type2 and config.type3.
If can find the postinst script in
/var/lib/opkg/info/test-deployment.postinst and execute it.
Since test-deployment is a new package, I would have expected
pkg_postinst_ontarget to be executed
How is the first boot detected on a poky image? Is there a way to detect if
.postinst scripts haven't been executed?
Thanks,
-Damien
