I mention this every time people bash NetworkManager on servers.

I have NM set up on all our servers.  Why?  Because the legacy
network-scripts service tries to bring up the interface once on boot.
We had a power outage to the entire floor of our datacenter and the
linux systems booted faster than the network infrastructure.  Any
linux system not using NM tried to bring up the interface, saw that
there was no connection, and gave up.  We had to physically reboot
those hosts.  Systems running NM dynamically brought up their
interface when the interface became active.
