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. - |
