Thanks and I would have never figured it out without your help. However, moving the binary to /opt didn't work either (I made sure there is empty /opt in the base too). Anything else I am missing?

Hi,
You need to build your extension with the binaries under either the
/usr or /opt hierarchies. Legacy locations like /bin and /lib are
ignored. This is explained in the systemd-sysext.8 manpage.
