Loads of distributions assisted that upstream works out of the box with systemd. That way the work is shared across distributions. Not sure why you make such a strange suggestion. Loads of work has been saved thanks to systemd. So much more is shared across distributions it's kind of crazy to look back.

It's not at all clear what you're talking about, honestly. First you talk about distributions, then a vague "we", then some weird "scrap and replace" nonsense. No idea who you mean with a sentence such as "we scrap and replace rsyslog". It really makes no sense, if there's a developer that works on rsyslog the work will continue. Distributions might change a default, but it didn't seem to be about distributions.

To make things a bit clearer I talked about all the benefits of having systemd across distributions, plus how the work is shared. This because you seemed to not understand the benefits that systemd has for distributions, in response to the "since distros don't optimally configure a program out of the box". Again, with systemd work it often allowed things to be done upstream. Configuring things in a distribution is a waste of time, previously distributions often wrote their own init scripts.

One person specifically mentions that it's nice when stuff is good by default. Complaining that it's some fault of the distribution completely misses the point: systemd allows stuff to be shared across distributions! No need to complain that either the default wasn't ok, the init script had a bug, etc. It's shared by default. Similarly, once a mistake is found, the bugfix can be made in one place.

That's the nice bit. Your weird comment isn't clear at all, plus completely misses what's nice about systemd for distributions.
