> systemd has been a net positive for the linux ecosystem. remember when you had to write bash scripts to start, stop, restart services and handle any other signals you want to send it?

Systemd was meant to replace Ubuntu's upstart, not sysv init. And it indeed systemd was better designed than upstart.

Sysv init is a horrendous hack. People should NOT use that. Upstart had limitations but is okay, and certainly much better than sysv init. Systemd is okay too (but has much more features).

Also as an historical note, both upstart and system was inspired by Apple's launchd.

NixOS was an early adopter of upstart but it later migrated to systemd (alongside Ubuntu itself)
