A minimal Linux init system, made in C.

Made by Breadtard who deleted the repo, then his account, then recreated both for some reason. All development is going on there. Give him a star or something.

To compile InitRC from source and install it, first make sure you have a C compiler and the Linux kernel headers. Then run either

make
sudo make install

to do it with make

or

sudo mv /bin/init /bin/init.old
sudo cc initrc.c -o /bin/init -O3

if you want to compile it manually.

On bootup, initrc will first mount the pseudofilesystems, then run /etc/initrc/rc, then /etc/initrc/networkrc, then run /etc/initrc/user. After killing TTY1, InitRC will run /etc/initrc/shutdown and then poweroff the machine.

initrc/rc is meant to start essenial services, such as the dbus, set the time, hostname, etc.

initrc/networkrc is meant to, well, start the network.

initrc/user is meant to run user-created scripts in the initrc directory that arent essential to the system bootup, so it gets ran as last.

initrc/shutdown is for stopping processes and preparing to shutdown. As an example, you can use this script to stop sshd before shutting down.

InitRC doesnt have default rc files, you have to make those yourself.

User scripts are a new feature in initrc v0.5. First, create your userscripts in /etc/initrc/, then in /etc/initrc/user add a line that starts it, for example:

#!/bin/bash
sh -c "/etc/initrc/userscipt-X" # you dont have to call it userscript-X but this is an example
exit
