I'm looking for an FAQ or info on how the auto start an application after a reboot (say coming back up after a power outage).

My application is written in Perl and I had it running 24/7 in older versions of SUSE 9 and 10. I am now using SUSE 12.3.

The application is called DX Spider (a ham radio application but no RPM). The method I used to autostart the application was with the following line in /etc/inittab:
DX:235:respawn:/bin/su -c "/usr/bin/perl -w /spider/perl/cluster.pl" sysop >/dev/tty7

How do I accomplish this in SUSE 12.3? Adding the above line to /etc/inittab appears to do nothing - at perl app does not start up after a reboot.
Thanks for the help (or telling me where to look).
