When your machine turns on or reboots, you want certain things to happen automatically. If the 'machine' is a web server hosting websites defined by [[Apache]] and also a database server running [[MySQL]], then naturally you would want Apache and MySQL to start automatically. In SysV-style systems that still use <code>init</code> and the rc.d run levels, you can use either <code>chkconfig</code><ref>http://linuxcommand.org/man_pages/chkconfig8.html</ref> (RedHat and derivatives) or <code>sysv-rc-conf</code> for Debian variants to make that permanent.
=== List services ===
So what are the services controlled by 'init' scripts?
<source lang="bash">
# the easy way
ls -l /etc/rc.d/init.d/
# using chkconfig
chkconfig --list
# for newer systemd controlled systems
systemctl list-units
</source>
Here is an example list of the services you might find on your machine:
# NetworkManager
# acpid
# anacron
# atd
# auditd
# autofs
# avahi-daemon
# avahi-dnsconfd
# bluetooth
