Hi Thomas,
on IRC recently you said:
23:24 < zigo> If you're just answering about update-alternatives, then you haven't paid attention to what I
wrote in the bug report.
23:25 < zigo> And IMO, missing the point ...
As I read the above, the systemd maintainers declined your suggestion to
add support for handling /usr/bin/systemd-sysusers with the alternatives
system, and you then requested the Technical Committee to overrule them.
If this is not the case, could you please state clearly what you want
us to decide.
Among other things, you later mention that a separate systemd-sysusers
package would be acceptable to you, pointing to #946456 . This avenue
doesn't seem to be exhausted yet?
