yes they are hard links, or at least thay can be. "info ls" will tell
you that the column between permissions and owner is the number of hard
links. That's the 2 in the OP's "ls -l" output that I highlighted in my
previous email.
Your own example below shows that most of your files in
networking/profiles/default are hardlinked 2 other times (3 hard links
total), most probably in networking/devices/ as well as network-scripts/ .
To confirm this try "ls -li" and compare the inode numbers.

this is not the "network service", as in what you get with "service
network stop|start|etc...." which runs /etc/init.d/network in a
predictable environment. That script knows nothing about profiles, and
doesn't care at all about /etc/sysconfig/networking/ .
your example uses system-config-network-cmd which is part of
system-config-network, which as I said uses the stuff in
/etc/sysconfig/networking/ .
