Lighttpd

Hello everyone. I want to recover the architecture of lighttpd by debugging it. For that I tried installing it from the source code by following the instructions given on :
"http://redmine.lighttpd.net/projects/1/wiki/InstallFromSource"

When I execute the second last and last instructions, I get an error/warning:

subtain@subtain-laptop:~/lighttpd-1.4.x/doc$ update-rc.d lighttpd on <---- command 1

update-rc.d: warning: lighttpd start runlevel arguments (none) do not match LSB Default-Start values (3 5)
update-rc.d: warning: lighttpd stop runlevel arguments (none) do not match LSB Default-Stop values (0 1 2 6)
usage: update-rc.d [-n] [-f]<basename> remove

update-rc.d [-n]<basename> start|stop NN runlvl [runlvl] [...] .
update-rc.d [-n]<basename> disable|enable [S|2|3|4|5]
-n: not really

The disable|enable API is not stable and might change in the future.

I am using Ubuntu (10.04.1 LT) on Sony Notebook (VPCEB31FD).

I am new to this field so please be kind. Looking forward for any help regarding this issue.

Thanks.
