[Pkg-xen-devel] Bug#1028251: xen: FTBFS when building xen binary packages for sid on x86_64

[Chuck Zmudzinski]

Source: xen
Version: 4.17.0-1
Severity: normal
Tags: ftbfs patch

Dear Maintainer,

Hi,

I needed to test a patch to libxl so I started by trying to build
xen from source on an up-to-date sid installation.

The build failed:

   debian/rules override_dh_missing
make[1]: Entering directory '/home/chuckz/sources-sid/xen/xen-4.17.0'
dh_missing --list-missing
dh_missing: warning: usr/lib/modules-load.d/xen.conf exists in debian/tmp but is not installed to anywhere

dh_missing: warning: usr/lib/systemd/system/xenstored.service exists in debian/tmp but is not installed to anywhere

Please note that this output is after editing the
line in debian/rules that is currently

dh_missing --fail-missing

with

dh_missing --list-missing

so the missing files only induce a warning instead of FTBFS.

So the workaround is this patch to debian/rules:

--- a/debian/rules      2023-01-08 16:36:01.605863417 -0500

I presume you know about this and plan to fix it before the
next upload, but perhaps a recent systemd update is causing
this so I am reporting it here.

I also request that if the missing systemd files cannot be
installed properly before the next upload of a new version
you apply a workaround such as this patch or another workaround
until the missing systemd files are installed and configured
correctly.

Kind regards,

Chuck
