* On some systems/configurations, dahdi init script may kick in
during the time that hotplug scripts are configuring spans.
* It may lead to a race since the init script runs "dahdi_auto_assign_compat"
which calls "dahdi_registration" and that tries to run
"dahdi_span_assignments auto ..."
* Use the newly-added "dahdi_span_assignments" "unmatched" operation.
* Now the "dahdi_auto_assign_compat" script only runs "dahdi_registration"
if there are no "unmatched" Astribanks.
* This prevents the race in fully configured systems.
The race may still exist on partially-configured systems.
Maintains the original registration order as was before span
assignments. Should allow seemless trannsition to
dahdi.auto_assign_spans=0
* The idea:
- We stop handling in udev the case of missing
/etc/dahdi/assigned-spans.conf
- Instead we rely on "registration_time" dahdi_device attribute from
DAHDI-linux
- Then, we can sort the devices and assign their spans in
/etc/init.d/dahdi
* Mechanics:
- From /etc/init.d/dahdi, we run a new 'dahdi_auto_assign_compat'
script (after "waitfor_xpds" etc.)
- In this script we "auto" assign spans of non-Astribank devices
- In the end of the script we run "dahdi_registration" which
does the same for Astribank devices.
