Hi Jochen,

I'm not able to reproduce the error, see below (1).

What version of oe-core/bitbake are you using?

I'm using the latest master branches:

oe-core: 64f9fd2a1e quilt: added less to RDEPENDS list
bitbake:  28b3f0d8  runqueue: Optimise build_taskdepdata slightly

What is the bbappend? Is it publicly clonable? What happens if you drop 
that addition?

I followed your steps above and mounted my image as follows:

$ fdisk -l mkefidisk-201908230902-sda.direct
