> That's funny, because the loudest voices all seem to be insisting that an unholy shitpile of init scripts a la SysV was the One True Unix Way and had been forever (which shows how young they are, but I digress).
The arguments I've seen are mostly that it's possible to write clean, composable, independent programs with solid, well-defined APIs between them, rather than the monstrosity that is the systemd project.
Want to replace journald with something else? The API for doing that is not stable, and I suspect the build system doesn't make it easy. Want to initialise kdbus under another init system? Even though it should have absolutely no dependency on systemd whatsoever, the component which does so is tied into systemd and can't be removed from it.
On the other hand, there's systems like nosh[0] which prove that you can build UNIX-y composable programs to solve many of the problems that systemd set out to solve. If you want to replace the logger, go ahead! If you want some component of it without using the whole init system, that's doable too. With only a little work, I'm sure it'd be possible to run much of nosh as non-PID-1.
(Note that I'm not suggesting anyone use nosh - the code is a tad weird and it's hard to find things, and the build system is extremely non-standard. However, it makes a useful proof of concept that the tightly-coupled systemd is not the only way to build something better than the SysV init system.)
