Writing Init Scripts

This document explains how to write openrc scripts, aka init.d scripts.

Needs to start with #!/sbin/openrc-run

Using the start/stop templates and special predefined variables:

description="My Example Daemon"
command="/usr/sbin/mydaemon"
command_args="--args-for-mydaemon"
start_stop_daemon_args="--args-for-start-stop-daemon"
pidfile="/var/run/mydaemon.pid"
stopsig="SIGTERM"

Using start-stop-daemon

To be written

start() {
    ebegin "Starting mydaemon"
    start-stop-daemon --start \
        --exec /usr/sbin/mydaemon \
        --pidfile /var/run/mydaemon.pid \
        -- \
        --args-for-mydaemon
    eend $?
}
