[gian1200]

After many trial and error, installing "expat" worked. Installing "libexpat" or "libexpat1" didn't worked.

Something like:

microdnf install -y expat

Is this the right approach, or should I do something else?

[gsmet]

I think we should just drop /lib64/libexpat.so.1 from the doc. If it wasn't installed by microdnf when installing freetype and fontconfig, it's probably because they don't depend on it anymore.

Would you be willing to create a PR to fix it?

[gian1200]

Sure, no problem. Let me test it on our side first, to confirm that it is no longer necessary (with a Quarkus app + quarkus-poi).
If everything go smoothly, then I'll create a PR.
