All UNIX like systems that use the sysvinit (System V Initialization) use
this. This is on UNIX V.4, Solaris, Red Hat, Mandriva, Ubuntu ...etc.

# cd /etc/rc3.d/
# ls
S10sysklogd
S19mysql-ndb-mgm
S20mysql
S20ssh
S25mdadm
S89cron
S99rc.local
S11klogd
S20makedev
S20postfix
S21mysql-ndb
S50proftpd
S91apache2
S99rmnologin

These are just symlinks to the real script that does the start and stop which
is in /etc/init.d/ for each service.

That does not mean it is not there, just that you did not come across it.

On Debian/Ubuntu, it is the update-rc.d that does it.

On Redhat and family there is chkconfig.

There is always the manual way as well:

ln -s /etc/init.d/somedaemon /etc/rc3.d/S42somedaemon

I am not saying this is the best or worst way, but the concept is used
elsewhere.
