Notes: This page is now deprecated, users who like the old SysVInit method should probably stick to OpenRC. (Discuss in Talk:Init Rosetta#)

This article draws a parallel between the old SysVinit and the current systemd initialization.

Keep in mind that you can always omit the .service and .target extensions, especially if you're temporarily editing the kernel parameters when bootloader menu shows up. Easier to remember, as well.
