IMO, "it might die at some > indeterminate time" isn't an excuse for not trying to get the "start > stuff up" part right. There is a way to get this wrong, namely, don't ever start the server. In this case, failure is guaranteed. But there's no way to get it "right" in the sense of "there's some kind of algorithm execution of which guarantees success": No matter if you start syslog first, last, or at some random position in a sequence of server start, it might or might not be ready by the time some other program tries to use it. If some program must not continue beyond the point where it tries to log a message unless the message is (at least) received by a logging process, some form of explicit locking has to be used to ensure that. _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
