Simple and fast init

Introduction

quickInit is a simple and fast init written in C (as for now).

Features

* TTY spawning
* Service spawning and killing

quickInit is in constant development. There will be more features.

Compiling

If you want to crosscompile, specify CC variable, otherwise skip it.

Example:

make clean
make CROSS_COMPILE="x86_64-linux-musl-"

Usage

TTY file

Create /etc/quickinit/tty. Example file:

tty1::respawn:/sbin/getty 38400 tty1
tty2::askfirst:/sbin/getty 38400 tty2
tty3::askfirst:/sbin/getty 38400 tty3

The format of the file is:

tty[0, S0, USB0 or whatever]:[runlevel]:[respawn askfirst once]:[command]

Runlevels are not supported as for now.

Services

Services are stored in:
/etc/quickinit/services/available - there are executable scripts or programs which must parse two parameters: start and stop. Other parameters are optional.
Example file:

#!/bin/sh

case "$1" in
start)    
  ;;
stop) ;;

restart | reload)
  "$0" stop
  "$0" start
  ;;
*)
  echo $"Usage: $0 {start|stop|restart}"
  exit 1
  ;;
esac

exit $?

/etc/quickinit/services/enabled - there are symlinks to the files from available directory.
Listing of example directory:

lrwxrwxrwx 1 bartek users   21 2020-08-28  K002mountvfs -> ../available/mountvfs
lrwxrwxrwx 1 bartek users   21 2020-08-28  S001mountvfs -> ../available/mountvfs
lrwxrwxrwx 1 bartek users   21 2020-08-28  S002localnet -> ../available/localnet

Syntax of the filename is [S|K][priority][name] where:

• S stands for start, K stands for kill
• Priority must be between 000-999 (three characters). If the number is lower, the service will be started/killed earlier
• name is the service name, same as the name of the file in the available folder
