Hello fellow users,

I am a relatively new Linux and Kubuntu user.  I am seeking a detailed
guide on how Kubuntu 14 starts and what configuration files are
referenced in an "out-of-the-box" installation before any system
administration packages get added.

For instance, what is the default, running on "bare metal" method that
process 0 spawns all the other processes on the system?  When does
each "basic" service come up?  By basic I mean how does the system
proceed through each run-level, when do disk checks start, when does
networking start, what starts networking, etc.

I get a little confused when dealing with init because there seems to
be two init services.  I'm not complaining.  I'm sure this is very
useful and I would like to understand how it works from the "ground up".

I have a similar problem with networking.  I have specified that
Network Manager should not manage any interfaces but when I do a "ps
aux | grep network" lo and behold I see that the dhclient has called
NetworkManager.  That's fine because networking works great.  Now I
want to know how and why :-)

If someone could point me to some good documentation on this I would
be very appreciative.  I have found some documentation (obviously
since I have a working system with a broadcom wireless adapter ;-) )
but I find there are a lot of details glossed over and a lot of hand
waving going on.

Thanks in advance for any pointers.


Best Regards,
Duane
