asterisk users - Aug 2016 - DAHDI on CentOS 7

What is needed to get DAHDI to start up correctly on CentOS 7 and systemd...
I am using DAHDI-linux-complete 2.11.1

I saw mention in my search that it has been fixed after 2.11.1 but cannot
find
what the fix is.

Thanks,

Jerry

On my Fedora 24 system, the "dahdi-tools" package contains an
old-style
init script  /etc/rc.d/init.d/dahdi, and this seems to work just fine with
systemd. I realize that CentOS != Fedora but if you have or can find an
init script for an older CentOS, it might work fine on CentOS 7. I can send
you the script file that I have, but of course I can't guarantee it will
work on CentOS.

seems to work. I copied the dahdi.init to /etc/rc.d/init.d/dahdi, run
chkconfig dahdi on and reboot
and modules are now loaded...

Thanks,

Jerry

"make config" should also install the init script.

if at first you don't succeed, skydiving isn't for you

There are some good reasons for that. But I'll start with recommending
to set auto_assign_spans=0 . All of our packages have a patch such as:

--- a/drivers/dahdi/dahdi-base.c
+++ b/drivers/dahdi/dahdi-base.c
@@ -7405,7 +7405,7 @@ int dahdi_assign_device_spans(struct dahdi_device *ddev)
 	return 0;
 }
 
-static int auto_assign_spans = 1;
+static int auto_assign_spans = 0;
 static const char *UNKNOWN = "";
 

Or simpler, applicable at runtime (module load time):

  echo options dahdi auto_assign_spans=0
>>/etc/dahdi/modprobe.d/dahdi.conf

For starters, this means you no longer need to disableautomatic module
loading for PCI cards (which was not needed for most systems anyway),
and that on its own avoids most of the need for the init script.

It also avoids unloading the modules at shutdown. Which is a good thing.
Do that, and report what problems you have. Because I don't seem to have
problems with my packages (on Centos 7 and Debian Jessie).
