SysVinit

Shares rank 3 of 9 init systems by recommenders

Simple, easy-to-understand init system that stays small and out of the way and is easy for newcomers to learn. Critics say its shell-script runlevel approach is hacky and brittle.

  • Simple to understand and learn

    “while it may have given people headaches and lacked some functionality, was IMHO simple to understand”

    Comment from 2 Feb 2026 in “Linux from Scratch Ends SysVinit Support”

    “I find it a lot easier than learning systemd, or learning anything else.”

    Comment from 26 Jul 2026 in “Systemd Linger”

    “it is clear and human-friendly, with easy uptake by newcomers”

    Comment from 2 Feb 2026 in “Linux from Scratch Ends SysVinit Support”
  • Small components that stay in lane

    “The thing I appreciated about sysv was that it stayed in its lane and didn't want to keep branching out into new parts of the system.”

    Comment from 2 Feb 2026 in “Linux from Scratch Ends SysVinit Support”

    “The whole point of sysv is the components are too small and too simple to make it possible for "showstoppers"”

    Comment from 2 Feb 2026 in “Linux from Scratch Ends SysVinit Support”
  • Reliable on servers

    “Run scripts worked. They always worked. They were simple.”

    Comment from 2 Feb 2026 in “Linux from Scratch Ends SysVinit Support”

    “SysVinit was... fine.. on servers.”

    Comment from 18 Sep 2026 in “Systemd is a suite of basic building blocks”
  • Familiar to Unix users

    “for personal preference, I am more traditional and favor SysVInit.”

    Comment from 2 Feb 2026 in “Linux from Scratch Ends SysVinit Support”

    “If people are accustomed to UNIX systems, the sysvinit is better.”

What people warn about

Each mark is one comment

  • Per-distro shell scripts are inconsistent

    “a bunch of shell scripts, each complex enough to support different commands, sort-of-declare dependencies, etc, is not such a great idea”

    Comment from 2 Feb 2026 in “Linux from Scratch Ends SysVinit Support”

    “With sysv, the difficulty depended on the local tools because the launching scripts could not be shared across Linux distributions.”

    Comment from 3 Feb 2026 in “Linux from Scratch Ends SysVinit Support”

    “the difficulty depended on the local tools because the launching scripts could not be shared across Linux distributions”

    Comment from 3 Feb 2026 in “Linux from Scratch Ends SysVinit Support”
  • Old code that lacks features

    “sysvinit is an old 90s application and its code does have some cruft built up over the years”

    Comment from 3 Feb 2026 in “Linux from Scratch Ends SysVinit Support”

    “even in the 90s it was notably behind, say, Windows NT 3 in a lot of ways which matter”

    Comment from 2 Feb 2026 in “Linux from Scratch Ends SysVinit Support”

    “a lot of people dismissed the sysvinit early on because it had no features”

    Comment from 4 Feb 2026 in “Linux from Scratch Ends SysVinit Support”
  • Abuses runlevels to start daemons

    “SysVInit is abusing runlevel scripts for starting daemons which has always been a hack to be able to resolve dependencies between daemons.”

    Comment from 3 Feb 2026 in “Linux from Scratch Ends SysVinit Support”

    “the way it abuses runlevels to start daemons was never intended by the original designers of init”

    Comment from 3 Feb 2026 in “Linux from Scratch Ends SysVinit Support”
  • Weak on laptops and desktops

    “Before you say "so does sysvinit", no it does not. It was janky-but-workable on servers and desktops in the 90s”

    Comment from 23 Mar 2026 in “I Hate: Programming Wayland Applications”

    “In contrast SysVInit worked ok on servers and sort of on desktops, but on laptops forget it.”
