Package: dracut-install
Version: 110-1
Severity: important
X-Debbugs-Cc: farblos@vodafonemail.de

Dear Maintainer,

As of package version 110-1, `dracut-install' does not support JSON:

,----
| [~]$ /usr/lib/dracut/dracut-install --json-supported
| JSON is not supported
`----

However, JSON support is a prerequisite to access the dlopen() metadata
for ELF files, which is a prerequisite for having access to systemd's
dynamic dependencies.

That, in turn, is a prerequisite to process dracut configuration options
`add_dlopen_features' and `omit_dlopen_features'.  These are used, for
example, in `/usr/lib/dracut/modules.d/10systemd/module-setup.sh':

,----
| config() {
|     add_dlopen_features+=" libsystemd-shared-*.so:audit,kmod,mount,seccomp,selinux "
| }
`----

Without that `libseccomp' is not automatically included in the initramfs
generated by dracut.  And without that one gets warnings like the
following during boot:

,----
| Feb 17 14:55:46 host01 systemd[1]: bpf-restrict-fs: LSM BPF program attached
| Feb 17 14:55:46 host01 systemd[1]: /usr/lib/systemd/system/systemd-udevd.service:56: System call bpf cannot be resolved as libseccomp is not available, ignoring: Operation not supported
| Feb 17 14:55:46 host01 systemd[1]: Queued start job for default target initrd.target.
`----

See also upstream issue
<https://github.com/dracut-ng/dracut-ng/issues/2252>, where @chewi
suspects that this is related to missing build dependencies.

Thanks for maintaining dracut packages for Debian!
