However, during libguestfs building I still see this line:

Get:37 http://deb.debian.org/debian buster/main amd64 systemd amd64 241-7~deb10u7 [3499 kB]

So it seems that it downloads the systemd package directly from debian and not using the one installed on the host docker.

If the compliation from source overwrites the Debian-installed systemd
