I checked on my Ubuntu machine

chkconfig --list NetworkManager
NetworkManager: unknown service

Ok what is the difference between the two  I mean network-manager and
networking?
In case of networking who is controlling the network and lan card?

Here after this message to understand it further I Googled about
initctl and the stuff you mentioned.
initctl list shows following things running
http://pastebin.com/LrzuzZ7S
I do not see bluetooth any where in above output.
Now I check  sysv-rc-conf shows bluetooth and a cross X marked on it
at run level 5.
So I feel that in run level 5 bluetooth is running on my system.

and when I do status bluetooth
then
status: Unknown job: bluetooth

where as if I do

 chkconfig --list bluetooth
bluetooth                 0:off  1:off  2:on   3:on   4:on   5:on   6:off

so this is very surprising as in above output you see 5:on where as
status wont recognize it.
I read man page of status (which is nothing but opening initctls man page)
