As long as the ISAR_RELEASE_CMD report= s the exactly same value for a single bitbake invocation, we are fine. The value itself doesn't matter and can also change across invocations of b= itbake. That's exactly the point of the patch to correctly detect changes to the en= vironment and reflect them in /etc/os-release. Just to make sure we are all on the same page: With this patch, ISAR_RELEASE_CMD is executed in a anonymous function of th= e image recipe. By that it runs at bitbake parsing time and sets the variable IMAGE_BUILD_I= D to the output of the command. As this variable is part of the metadata, it must not change during a singl= e bitbake invocation. Otherwise bitbake reports "metadata is non-deterministic". However, it is perfectly fine to change the value across builds (e.g. incre= mental ones and even without a single modification to a recipe). That will become relevant once SState is enabled: In case the rootfs is cached, the ISAR_RELEASE_CMD was not executed again, = leading to invalid information in /etc/os-release (e.g. by missing a tag). This is fixed by the patch. >=20 > Workarounds are to tag more often or to clone deeper. I am not sure git > describe can be told how many commits to consider in the past. So its out= put > might simply differ depending on how deep you cloned. What you describe here is just about unexpected results in /etc/os-release,= because the expected git tag is not in the history. That's a different story and cannot be addressed by ISAR, but only by the u= ser. Felix >=20 > Henning
