SysV init runlevel configuration tool for the terminal sysv-rc-conf provides a terminal GUI for managing "/etc/rc{runlevel}.d/" symlinks. The interface comes in two different flavors, one that simply allows turning services on or off and another that allows for more fine tuned management of the symlinks. Unlike most runlevel config programs, you can edit startup scripts for any runlevel, not just your current one.
