The reason for starting a new + one was mainly dissatisfaction with the existing ones. Other Projects + that have been considered include: + + - systemd + Contains a lot of good ideas, but it is HUGE. It has tons of + dependencies. It implements tons of things that it simply shouldn't. + It has a horrid, "modern", python based, hipster build system. + It's simply too damn large and complex. + + - SystemV init + A bad combination of unnecessary complexity where it isn't needed and a + complete lack of abstraction where it would be needed. Shell script + copy and paste madness. There are reasons people started developing + alternatives (other than "hurr-durr-parallel-boots"). + + - upstart + Seems nice overall, but needlessly big and complex for the intended + use case in Pygos. Would have needlessly added D-Bus to the system. + + - OpenRC + Was already integrated into Pygos. Things turned out to be broken. + Upstream developers did not accept fixes (after ignoring them for weeks + and preferring typo fixes instead). Complaints from other people who + tried to contribute fixes were observed on Github. Complaints from + package maintainers about deteriorating code quality were observed + on the official IRC channel. Documentation is non-existent. + + - daemontools and similar (runnit, s6, minit, ...) + The sixties are over. And even code from that era is more readable. The + source code for those projects should better be tossed out the window and + rewritten from scratch. If you are a first semester CS student and you + hand something like this in as a homework, the best you might get is a + well deserved slap on the back of your head. + + - busybox init + Nice and simple. Probably the best fit if the rest of your user space is + busybox as well. + |
