I've just built a container "FROM ubuntu:plucky", which has inkscape
instead of imagemagick + rsvg-convert.
I don't see any font issue at 4/11 of this series under the container
(I'm using podman).

Furthermore, after I applied both of your series and the change for
parallel runs of xelatex/latexmk and reverting the 5/11, I don't see
any issue.

Which strongly suggests 5/11 is not fixing any realistic issues.

FWIW, Dockerfile I'm using for building the container is derived from the
one I've been taking care of since 2021 as a LaTeX advisor to perfbook.

If you are interested, here is its repo of Paul:

    git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/perfbook.git

You might be interested in seeing docker/Dockerfile.

I think there is something you are missing in the boot strapping phases
of building your container.

Just my wild guess.

Thanks,
Akira
