Why is that even necessary? Shutdown scripts could selectively background+detach things that need to survive killing of VDR and the script themselves, if any. > and only because of that the script can display messages via SVDRP. Hmm, why wouldn't a non-background, non-detached script called by VDR be able to do that? > Some shutdown scripts do set > error levels, but there's no common definition about the meaning of > error levels. Right, my post was about mentioning a possibility to add such common definitions if found feasible. > Defining error levels for the shutdown script would > thereby be potentially incompatible to existing scripts. Sure. Authors of such scripts get to keep both pieces if their scripts break due to use of undocumented features ;). I suppose changing the shutdown script not to run background+detached would probably be a source of more incompatibilities though, and ones that script authors would not be responsible for. _______________________________________________ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
