# Minirc

Warning: Arch Linux only has official support for systemd. When using Minirc, please mention so in support requests.

Minirc is a init script for busybox init maintained by some people on github. Minirc is script based and does not work with other init systems.

## Installation

Minirc is available in the AUR. For details on init components, see Init.

Install the minirc-gitAUR package. Minirc replaces /sbin/init so it removes systemd-sysvcompat. It will also conflict with SysVinit, if you have it installed.

Also if you are using a desktop environment, It might help to install ConsoleKit or elogindAUR.

## Configuration

The main configuration file is /etc/minirc.conf. Startup commands are put in /etc/minirc.local, Shutdown commands are put in /etc/minirc.local.shutdown. Minirc services are enabled by the DAEMONS and ENABLED lines in /etc/minirc.conf.

The local startup and shutdown files are just bash scripts.

To create the local startup and shutdown files you just run

    touch /etc/minirc.local
    touch /etc/minirc.local.shutdown
    chmod +X /etc/minirc.local
    chmod +X /etc/minirc.local.shutdown

The daemons enabled by default are syslog-ng, crond, dhcpcd, and sshd.

If the packages aren't installed then you will get a warning on bootup unless you disable them.

## Gettys

The gettys are defined in the file /etc/inittab, By default getty is started on ttys 1 through 4.

In order to enable/disable gettys, you just put this line in /etc/inittab.

    tty2::respawn:/sbin/agetty -8 -s 38400 tty2 linux

Just replace tty2 with the tty, you want getty to start on. If you want init to ask you before starting the gettty, then replace respawn with askfirst.

### Custom daemons

You specify custom daemons on the custom_start, custom_stop, and custom_poll functions in /etc/minirc.conf. You just follow the syntax that the other daemons are using. By default there are no custom daemons, these are the ones I put in.

    custom_start () {
        case "$1" in
        NetworkManager)
            /usr/bin/NetworkManager ;;
        lightdm)
            sleep 1 ; /usr/bin/lightdm ;;
        *)
            default_start "$@";;  # keep the default as fall-back
        esac
    }

    custom_stop () {
        case "$1" in
        NetworkManager)
            killall NetworkManager;;
        lightdm)
            killall lightdm;;
        *)
            default_stop "$@";;  # keep the default as fall-back
        esac
    }

    custom_poll () {
        case "$1" in
        NetworkManager)
            pgrep NetworkManager > /dev/null;;
        lightdm)
            pgrep lightdm > /dev/null;;
        *)
            default_poll "$@";;  # keep the default as fall-back
        esac
    }
