Yes, taste it is :) Scripting has its place, but from my extensive reading of systemd docs and some of the old sysv startup scripts (for postfix and various others over the years), give me systemd unit files any day! Preference. Mine. For games customization, scriptability sounds to make a lot of sense to me. Might also make sense for some system daemons, I dunno. But where a bunch of flags can be specified, and satisfy typical/all daemon config needs, declarative unit files appear *much* cleaner to my simpleton eyes. Time will tell I guess, but I strongly suspect that in daemon land, unit files will prove to very successfuly cover the majority of configuration use cases, with only rare/occasional call outs to "user authored" scripts. Just got a gut feeling on this one. Regards, Zenaan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
