Further observation: doesn't seem to be a timing problem / race condition right after system init as this behaviour persists way beyond boot stage, ie. is reproducible all along the way.
What would be of great help to track this down is what exit code 127 from the backend exactly means. Esp. as the backend exits before ANY logging information is produced... Here's what initctl produced when setting the log level to debug: Jan 3 08:10:58 htpc kernel: [ 1443.013593] init: mythtv-backend goal changed from stop to start Jan 3 08:10:58 htpc kernel: [

description: Strange problem with the backend during upstart on Ubuntu oneiric: the syslog tells me that the backend respawns too quickly and thus gives up on trying to start it via upstart. Steps to reproduce: 1) Reboot system 2) Check with 'ps' and the syslog I changed the interface from lo to eth0 in the pre-conditions and also changed .5 to 60 in the script sections but to no avail...
