Re: "Back off" setting for crashing services with s6+openrc?

pect delay magic in run or finish scripts. I mean, imagine you have to debug why a service doesn't start. Reading the run or finish scripts for that is not that fancy.

ce to have supervision for all of these instances instead of doing it without. Of course I know how to do it without. Is there a pattern around to solve this with s6 and supervision? Best Regards Oli -- Automatic-Server AG • Oliver Schad Geschäftsführer Hardstr. 46 9434 Au | Sc
