I maintain a matrix of integration tests to build images in OBS. One part of
the tests also builds images using device mapper features like dm-crypt or
dm-raid

For building such images the OBS worker environment (kernel + initrd) requires
support for device mapper modules.

For building in OBS the kernel-obs-build package is used. All tests were
successful until an update/change of the kernel-obs-build package happened:

    kernel-obs-build-5.18.2-1.1

For details on the error please visit:

The image builds started to fail ~2weeks ago

Would be great if this could be fixed.

Thanks much
