Hi,
your package python3.9-minimal declares a dependency (Suggests) on
binfmt-support and ships binfmt-support configuration files in
/usr/share/binfmts/.
systemd provides a builtin, cross-distro facility named systemd-binfmt to
register binary formats.
You can read more about it at
https://www.freedesktop.org/software/systemd/man/systemd-binfmt.html
https://www.freedesktop.org/software/systemd/man/binfmt.d.html
https://www.kernel.org/doc/html/latest/admin-guide/binfmt-misc.html
The systemd package provides a dpkg file trigger so it is sufficient to
simply install configuration files in /usr/lib/binfmt.d/, no
modifications in the maintainer scripts are necessary.
The attached patch ships a configuration file for systemd-binfmt which
will automatically enable binfmt support for python3.9 without requiring
further dependencies.
Regards,
Michael
