[rancid] Alcatel script, not parsing the commands and/or output well (/partially)

I also have “3.99.99” on the system to compare the output. The regular version on the system is 3.6 it seems.
But, the noklogin works after modifying the u_prompt and p_prompt. When running rancid -d -t sros <devicename>
it wants to execute commands that are not available at all on the Alcatel.

The ones that I use from Burgalio’s :

        {'show chassis'                 => 'ShowChassis'},
        {'show system'                  => 'ShowSystem'},
        {'show module'                  => 'ShowModule'},
        {'show stack topology'          => 'ShowStackTopolgy'},
        {'show lanpower 1'              => 'ShowLanPower'},
        {'show lanpower 2'              => 'ShowLanPower'},
        {'show user'                    => 'ShowUser'},
        {'ls'                           => 'GenericParse'},
        {'ls certified/'                => 'GenericParse'},
        {'ls working/'                  => 'GenericParse'},
        {'ls switch/'                   => 'GenericParse'},
        {'ls network/'                  => 'GenericParse'},
        {'show vlan'                    => 'ShowVLAN'},
        {'show interfaces status'       => 'ShowInterfaces'},
        {'show running'                 => 'ShowConf'},
        {'show configuration snapshot'  => 'ShowConf’},

which does not match:

xecuting noklogin -t 90 -c"show system information;file type bootlog.txt;show redundancy synchronization;show chassis;show chassis environment;show chassis power-supply;show chassis power-management;show card state;show card detail;show debug;show bof;admin display-config index;admin display-config” <devicename>

Do note that it seems that the SROS is on a very different architecture based then what my Omniswitches use. So it seems incompatible to start with, where the alu* scripts might not entirely work with every command on the OS6000 that I have, but most of them are accepted in older (legacy) components but also on the newer
