asterisk users - Oct 2014 - Ubuntu 12.04 LTS / Asterisk / apt-get upgrade / exclude packages

Hi,

I have Asterisk 11 with DAHDI (Sangoma E1-Card) running on Ubuntu 12.04
LTS. Asterisk and DAHDI-Drivers are installed from source.

When doing an "apt-get upgrade" the system packages will be update but
sometimes Asterisk is broken. Which packages do I have to exclude when I
do not have time to recompile Asterisk/Dahdi each time? libc?
Kernel-Packages?

Thanks so far!

Can you describe what is broken?

The way things are set up is that you have to compile the wanpipe drivers always
against the
current versions of the kernel and DAHDI. You could change that with a pretty
high risk of
breaking things, mainly due to frequent changes in the network related parts of
the kernel.

I have never seen something break, except for kernel updates, but my systems are
RedHat based. I
doubt that the Debian based systems are much different as far as interface
changes are concerned
for a certain release. My guess is that you should be fine if you do not execute
"apt-get
dist-upgrade".

DAHDI is basically a set of kernel modules, which *by design* work only with 
the exact kernel for which they were compiled; so avoid any upgrade to the 
kernel if you don't have time to rebuild DAHDI.

C library changes potentially could require anything to be recompiled; but in 
practice almost invariably don't, precisely because of how much breakage
would
potentially be caused.  If a C library update requires recompilation of other 
packages then either there has been a Flag Day  (and not the sort where mean 
people stay indoors!)  or you're running Gentoo.

I believe there is a way in Debian, and therefore probably Ubuntu, to have 
some script execute automatically following a kernel update.  So you might 
even be able to have DAHDI self-rebuild following a kernel update.
