Change services bootup runlevel

chkconfig for Ubuntu (sysv-rc-conf)

There is an alternative for editing runlevels that can be used just like chkconfig (Red Hat):
http://sysv-rc-conf.sourceforge.net/

To install & run:

# sudo apt-get install sysv-rc-conf
# sudo sysv-rc-conf

Excerpt from the manual:
DESCRIPTION
sysv-rc-conf gives an easy to use interface 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. It’s a replacement for programs like ntsysv(8) or rcconf(8).
sysv-rc-conf can also be used at the command line when the desired changes to the symlinks are already known. The syntax is borrowed from chkconfig(8).
