</I>>>><i> This happens whenever a package with systemd support is updated:
</I>>>><i>
</I>>>><i> installation de nginx-1.0.14-1.mga2.x86_64.rpm depuis /var/cache/urpmi/rpms
</I>>>><i> Préparation ... #############################################
</I>>>><i> 1/1: nginx #############################################
</I>>>><i> Warning: Unit file of created job changed on disk, 'systemctl --system
</I>>>><i> daemon-reload' recommended.
</I>>>><i>
</I>>>><i> First question: should we not make rpm-helper automatically do it, if
</I>>>><i> not already done ?
</I>>>><i>
</I>>>><i> Second question: could we ensure the message is not displayed if handled
</I>>>><i> automatically ?
</I>>><i>
</I>>><i> Looks it is handled (somewhat):
</I>>>><i> [<A HREF="https://www.mageia.org/mailman/listinfo/mageia-dev">anssi at sigma</A> ~]$ cat /var/lib/rpm/filetriggers/systemd-daemon-reload.filter
</I>>>><i> ^./lib/systemd/system/
</I>>>><i> ^./etc/systemd/system/
</I>>>><i> [<A HREF="https://www.mageia.org/mailman/listinfo/mageia-dev">anssi at sigma</A> ~]$ cat /var/lib/rpm/filetriggers/systemd-daemon-reload.script
</I>>>><i> #!/bin/sh
</I>>>><i> if /bin/mountpoint -q /sys/fs/cgroup/systemd; then
</I>>>><i> if [ -x /bin/systemctl ]; then
</I>>>><i> /bin/systemctl daemon-reload >/dev/null 2>&1 || :
</I>>>><i> fi
</I>>>><i> fi
</I>><i>
</I>><i> Yup, the filetrigger handles this generically.
</I>><i>
</I>>><i> However, maybe it is done too late? The Warning comes from %post, while
</I>>><i> filetriggers are run at %posttrans time.
</I>>><i> Maybe daemon-reload should be run in %_post_service instead?
</I>><i>
</I>><i> I thought I had put it in %_post_service... hmmmm.
</I>><i>
</I>><i> I guess it should go before this line:
</I>><i> /bin/systemctl --quiet try-restart $units
</I>><i>
</I>><i>
</I>><i> The file trigger is to catch when a unit changes. That may or may not
</I>><i> cover services specifically (could be socket or mount units etc.) thus
</I>><i> %_post_service may or may not be called. So I think the file-trigger is
</I>><i> still valid.
</I>><i>
</I>><i>
</I>><i>
</I>><i> As for silencing the message I agree. Not quite sure how that message is
</I>><i> generated however....
</I>
Well, no need to silence the message if you fix the issue that causes it
to appear in the first place :)
