Bug#1012354: Please add support for systemd-binfmt

[Michael Biebl <biebl@debian.org>]

Package: sbcl
Version: 2:2.2.3-1
Severity: wishlist
Tags: patch
User: pkg-systemd-maintainers@lists.alioth.debian.org
Usertags: systemd-binfmt

Hi,

your package sbcl declares a dependency (Recommends) on binfmt-support
and ships binfmt-support configuration files in /usr/share/binfmt/.

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 adds support for systemd-binfmt and adjusts the
dependency on binfmt-support accordingly, so binfmt-support is no longer
installed automatically if systemd is already installed.

Regards,
Michael
