Yes, it is:

$ ls -l /etc/dahdi/assigned-spans.conf*
-rw-r--r-- 1 root root 428 Jan 14 17:47 /etc/dahdi/assigned-spans.conf
-rw-r--r-- 1 root root 428 Jan 14 17:47 /etc/dahdi/assigned-spans.conf.bak

$ sudo dahdi_span_assignments -v auto
auto-assign /sys/bus/dahdi_devices/devices/pci:0000:0a:00.0

$ sudo dahdi_genconf -v
Default parameters from /etc/dahdi/genconf_parameters

Generating /etc/dahdi/system.conf
Generating /etc/asterisk/dahdi-channels.conf

This seems to do the trick.

Did something gone wrong during the package installation? This could be investigated by reinstalling from scratch is this could be of any help.
