NetworkManager and upstart.

I dislike complexity.   Would like to see much more
documentation too (maybe my fault).   We don't even
like the gui.  Although, more and more, we are forced 
to use it.

I understand the goals of NetworkManager (ease of use 
for laptops, non-technical users, and compatability
for "home" user's taste- wireless, dhcp, plug and
play with devices being added/removed...), but, with
these features comes complexity.   Servers generally 
don't need it.

And, I don't like that RHEL6 install script forces me to 
use it by default.

After it runs, I have a hard time "undoing" it.

/etc/init.d/network script in Fedora 11/12 (?) was still
overwriting resolv.conf after:

# chkconfig --level 2345 NetworkManager off

RHEL6 seems to as well, in some cases.

Perhaps I just need coaching on how to completely 
de-install it all.  

I also understand the goals of "upstart": More powerful
features; boolean/non-sequential branching (as opposed to 

But, I don't need these features.   At least not yet!
Simple, sequential startup works fine for our current 

I like to ask my system "what runlevel?", and get an 
honest answer.  Or, if "runlevel" going out the window, a
new mechanism/paradigm which is understandable, usable,
friendly, and configurable from a command line and gui.

My gut tells me "upstart" (much like in Solaris 10) is such
a huge change that it will be problematic unless improved
and simplified for future RHEL releases.

Okay, I'll bite..  What do you dislike about NetworkManager?  Except for
the fact that one first-run you need to configure it via the UI, once
it's configured you can set it up to auto-connect at boot time.  You can
still set up a static network config the way you did before, and indeed
you can specify that NM not control an interface.
