---------------------

I disabled the service, since i think i don need it.

Hmm, so you disabled it? Where's the problem then?

I disabled it, but there are still some messages being feed to the logs.

ls: cannot access /etc/systemd/system/dbus-org.freedesktop.Avahi.service: No such file or directory

So it was it really disabled?

I am sure i executed this previously:

# systemctl disable  avahi-daemon.service
rm '/etc/systemd/system/dbus-org.freedesktop.Avahi.service'
rm '/etc/systemd/system/multi-user.target.wants/avahi-daemon.service'
rm '/etc/systemd/system/sockets.target.wants/avahi-daemon.socket'


The problem is that a that time i did this as sugested by the previous messages. Because if i am not using
that service, i want to get rid of those 'error/?' messages.

> Hmm, so you disabled it? Where's the problem then?

Well, i am not sure, after *1 i opened (Bug 697185 - F15 systemd issue with non-existent units[...]).
Are 'avahi-daemon.service' and 'dbus-org.freedesktop.Avahi.service' the same 'service' ? 
Since i can only disable the first and the second appears in the messages, and when taking
into account cases like *1, i feel a bit confused, since i am no expert in systemd. 
(i have used it since the alpha, so it is really not much time). The logs says to check status for the second...

I reinstalled the system, now running beta.

I want to get rid of those errors in my messages, by disabling avahiXXXXXXXXXX but i cant. Or at least
i cannot get rid of the messages.

> Hmm, so you disabled it? Where's the problem then?

The problem is those horrible messages i want to get rid off. why the need to output 
any "[...]Activation via systemd failed for[...]" messages for a "supposedly" disabled
unit / service ?

If this is just about getting rid of syslog messages, then let's reassign this to dbus which generates them. It should simply suppress them.

hi, 
you got same kind of messages with NetworkManager, on a server, I disable NetworkManager

In my case avahi is no installed :

# chkconfig --list | grep ahi

Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.

# systemctl | grep ahi
#

but the message :

Sep  9 18:34:10 xxxx dbus: [system] Activating via systemd: service name='org.freedesktop.Avahi' unit='dbus-org.freedesktop.Avahi.service'

Sep  9 18:34:10 xxxx dbus: [system] Activation via systemd failed for unit 'dbus-org.freedesktop.Avahi.service': Unit dbus-org.freedesktop.Avahi.service failed to load: No such file or directory. See system logs and 'systemctl status dbus-org.freedesktop.Avahi.service' for details.

Then, why systemd is trying to activate Avahi, if it is not installed ?

Guillermo, i have found a workaround to that messages in /var/log/messages

1) go to /usr/share/dbus-1/system-services
2) rename file org.freedesktop.Avahi.service to something like :
      org.freedesktop.Avahi.service.copy

That is it. The messages goes out.

BUT :

a) What else if you enable Avahi again ?
b) The management of this file was not a atribution of
   the systemctl command ? That means, when i execute :

# systemctl disable org.freedesktop.Avahi.service

i will believe that Avahi is off and systemd will not try start it.
Am i wrong ?

PS.
I'm just a simple user and don't know systemd deeper. Actually, a have just a vague idea of what systemd is. Maybe it is not a bug at all, and we MUST leave things as they are.

Please David, give us the light !

Cheers

org.freedesktop.Avahi.service

systemctl status avahi-daemon.service

How I do know if it is enabled or disable on startup ? 
systemctl is-enabled avahi-daemon.service 
don't say nothing ! (yeah this could be more friendly ) 

Thanks,

Hi Sergio.

# systemctl --full --all

will give you the entire picture. Filter with grep if you want.

Hey david !

Any clues ?

systemctl --full --all | grep avahi
avahi-daemon.service      loaded active   running       Avahi mDNS/DNS-SD Stack
avahi.service             error  inactive dead          avahi.service
avahis.service            error  inactive dead          avahis.service
avahi-daemon.socket       loaded active   listening     Avahi mDNS/DNS-SD Stack Activation Socket

where is write if is enabled or disable on startup ?

Hi Sergio !

I don't know exactly.

I think all systemd services are started somewhere at startup. But i am a bit confused with systemd, yet.

maybe :

# chkconfig --list | grep -i avahi

(Please, see the man pages)

But this thread is about :

- Disabling avahi
- systemd starting avahi anyway.

If you want it disabled, just disable it with systemctl command. And "hack" the startup by renaming 

/usr/share/dbus-1/system-services/org.freedesktop.Avahi.service

to something else.

would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

The process we are following is described here:
