NM_CONTROLLED=

Depending upon what you want to do.

Will you ever use a Cell card on this system?
Will you ever change IPs temporarily, or often?

It can be useful to let Network Manager manage the ifcfg-eth0 file.

If you set:
     NM_CONTROLLED=yes

Network Manager will 'keep and eye' on the file, and automatically make 
any changes you specify there, without having to restart anything.

This also allows Network Manager to decide if that route is still 
appropriate if you plug in and play with another network device, such as 
a cell card, a USB dongle, wireless dongle, bluetooth dongle to use your 
cell phone, etc etc

You can also play tricks with network based applications like ntpd, and 
tell Network Manager only to run ntpd if eth0 is up and active.

Lots of options with NM in control, but on a fixed IP stationary 
workstation or server, it is still best to continue to use just the old 
network scripts and turn NM off.

Good Luck!
