Bug#935582: dahdi: dahdi_genconf fail with .../spantype: No such file or directory

[Petter Reinholdtsen]

Package: dahdi
Version: 1:2.11.1-3
Severity: important

I am trying to set up Asterisk on Debian Buster, and discovered that
dahdi_genconf do not work, possibly because 'dahdi_span_assignments
list' fail.

This is the output when trying to configure dahdi:

# dahdi_genconf -vvvvv
Default parameters from /etc/dahdi/genconf_parameters
Empty configuration -- no spans
Generating /etc/dahdi/assigned-spans.conf
cut: '/sys/bus/dahdi_devices/devices/pci:0000:01:05.0/spantype': No such file or directory
Empty configuration -- no spans
Generating /etc/dahdi/system.conf
Empty configuration -- no spans
Generating /etc/asterisk/dahdi-channels.conf
#

And this is the output from the failing command:

# dahdi_span_assignments list
cut: '/sys/bus/dahdi_devices/devices/pci:0000:01:05.0/spantype': No such file or directory
#

The cause for this message seem to be that 'spantype' is no longer
available from the kernel driver.  There is a file named
'dahdi_spantype', perhaps it can be used?  I tried to modify the scripts
to use dahdi_spantype instead, and the error message went away, but
still no channels defined. :(

This is the patch I applied:
