Source code of linux init process [closed]

Question

I want to figure out what is exactly going on in init process (/sbin/init) of Linux, but it is quite hard to find one. Could you tell me who maintains the source code of init process?

Answer 1

It depends on Linux version. Traditionally, sysvinit was used.

These days, many Linux distros use upstart.

Some others, like Fedora, are using systemd.

Answer 2

You can download the source code of the sysvinit package here.

Note that some Linux distributions do not use System V Init anymore. For instance, Debian, Fedora and Ubuntu use upstart instead.
