Debian system startup script
The Debian Gnu/linux uses the SYSV module as the system initial script. Like RH, Debian uses an extended SYSV module, while the Slackware is primarily BSD-based, and several handy scripts are written to use the SysV module.
Locating the SYSV directory
The Debian Gnu/linux, like most systems using the SysV module, stores the relevant directories in/etc directory. That is, the SYSV directory/etc/init.d is the script itself, and/etc/rc1.d,/etc/rc2.d until/ETC/RC6.D is a special run-level directory.
