#91272 — Bug#1128349: dracut-install: Potenial missing build dependencies, dracut-install built without JSON support

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!

Thanks for reporting it. I'll fix that with the next Dracut upload in
the coming days.
