Hi,
Ubuntu does not carry chkconfig any more ..
besides the standard
update-rc.d apache2 defaults
or
update-rc.d apache2 remove
There is a cool tool called : sysv-rc-conf.
This tool can be installed using :
sudo apt-get install sysv-rc-conf
On its own the command opens a cool ncurses interface like this :
It can Also be used in scripts as :
sysv-rc-conf atd <on or off> and --levels;
man sysv-rc-conf
Will give you some love..
