A recent change in meta-mender causes build failure when ARTIFACTIMG_FSTYPE is set the squashfs:

For now, my workaround is to revert this commit in meta-mender:

cfdeb3d1 Avoid populating rootfs partition B to save space when compressing.

Hey @cveilleux, can you try the fix suggested in MEN-5285: Avoid empty partitions for squashfs. Doesn't support them. by kacf · Pull Request #1559 · mendersoftware/meta-mender · GitHub ?

@kacf I have applied MEN-5285: Avoid empty partitions for squashfs. Doesn't support them. by kacf · Pull Request #1559 · mendersoftware/meta-mender · GitHub on top of mender’s dunfell branch and removed the revert of cfdeb3d1

The build works fine now, it fixes the problem.

Thanks!
