Those configured for the runlevel (usually "2" these days) in
/etc/rc?.d/ - read `man 8 init`. `ls -l /etc/rc?.d/`

Instead of creating symlinks in /etc/rc2.d/ manually one usually
configures those with `update-rc.d` (`man update-rc.d`). There's also
some GUI's to configure the system-V init scripts, but I don't know what
they're called these days..
