I am packaging camsource - a webcam-streaming software. I've just added an init script that gets installed with dh_installinit. However on this testing box where I check the packaging in chroot does not have a webcam attached, so the daemon is missing a device and not starting correctly:
Unable to open /dev/video0 (No such device) Failed to open device for <camdev name="default"> invoke-rc.d: initscript camsource, action "start" failed. dpkg: error processing camsource (--install): subprocess post-installation script returned error exit status 1 Errors were encountered while processing: camsource I'm not sure what would be best practice to avoid those errors, because the admin might have to configure the video device first anyway (though the default /dev/video0 is usually a nice guess). Have an /etc/default/camsource where the admin has to enable the daemon setting $START_CAMSOURCE? The init script could display something like "Please configure camsource using /etc/camsource.conf and enable it in /etc/default/camsource if you want to use init to start it." if not enabled... Use --no-start with dh_installinit and stop the daemon manually on uninstall in prerm? Other? -- Balu
