Even bigger question: The architecture has to be correct. Systemd is trying to solve dependencies between applications by considering simple FD activity (by acting as a proxy for applications). However, there almost certainly are more complex, logical dependencies which are not visible to systemd, and hence which apps will still have to deal with and resolve between themselves. In short, we will still need that app-layer. We need to consider how that impacts architecturally on the worth of solving a subset of problems in a lower layer. regards, -- Paul Jakma p...@jakma.org Key ID: 64A2FF6A Fortune: I'm not a real movie star -- I've still got the same wife I started out with twenty-eight years ago. -- Will Rogers -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel

Quite often this is simply bad use of tools. Often large parts of the shell script around the AWK use could have been easily done /within/ the AWK script. Indeed, I'm sure have seen boot systems that were done as AWK scripts. ;) AWK is a relatively capable line/string/stream processing programming language, it's quite sad so many don't realise this and only use it to print fields by number. regards, -- Paul Jakma p...@jakma.org Key ID: 64A2FF6A Fortune: In every non-trivial program there is at least one bug. -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel
