I spent the better part of two hours trying to discover why I could not configure br0 to start after modifying /etc/sysconfig/network-scripts following my previously succesful notes. I finally deleted ifcfg-bro and used the existing ifcfg-eth0 and -eth1 scripts to at least get a network connection working. When I start the network service I only saw l0 and eth0 start as eth1 is disabled. However, when I did an ifconfig I saw that br0 is configured as well, but not by me.
Looking for br0 in the file system led me to the directories listed above. I do not recall seeing these before and the only difference between this CentOS box and the previous virtual host I installed is that this time I selected the virtual host install option instead of minimal install. Evidently this was a misstep on my part. One that I doubt I shall repeat.
My questions are: What are these duplicate, and identical, files doing in multiple places on my system; and why are they evidently interfering with the normal processing of /etc/sysconfig/network-scripts through the service utility?

My questions are: What are these duplicate, and identical, files doing in multiple places on my system;
those are hard-linked, most likely the same file in both subdirs (not identical files, a single file hard-linked twice)
the /etc/sysconfig/networking/* subdirs can exist on C5 as well, I think they're used by system-config-network
and why are they evidently interfering with the normal processing of /etc/sysconfig/network-scripts through the service utility?
on a C6 machine I have those dirs are empty, as on your C5 system. I probably never used system-config-network on it. Networking through /etc/init.d/network functions fine without them.

Files in /sysconfig/networking/profiles/ are not hardlinks. As the last name suggests, those are files from Profiles. And using "ll" command is blinding you. If you use "ls -lR /etc/sysconfig/networking/profiles/* :
/etc/sysconfig/networking/profiles/default: total 44 -rw-r--r--. 2 root root 271 Sep 3 22:00 hosts -rw-r--r--. 3 root root 315 Jun 30 13:39 ifcfg-br0 -rw-r--r--. 3 root root 248 Jun 30 13:39 ifcfg-br0:1 -rw-r--r--. 3 root root 248 Jun 30 13:39 ifcfg-br0:2 -rw-r--r--. 3 root root 248 Jun 30 13:39 ifcfg-br0:3 -rw-r--r--. 3 root root 248 Jun 30 13:39 ifcfg-br0:4 -rw-r--r--. 3 root root 248 Jun 30 13:39 ifcfg-br0:5 -rw-r--r--. 3 root root 211 Jun 30 13:39 ifcfg-br0:6 -rw-r--r--. 3 root root 211 Jun 30 13:39 ifcfg-br0:7 -rw-r--r--. 3 root root 229 Sep 4 01:06 ifcfg-eth0 -rw-r--r--. 1 root root 286 Sep 4 00:56 resolv.conf
Both C5 and C6 have "network" service able to create and switch to multiple profiles. For example, switching to profile "WiFiKuca" is done with:
"system-config-network-cmd -p WiFiKuca -a"
In sub-directories of /etc/sysconfig/networking/profiles/ are stored originals of your configuration, and /etc/sysconfig/network-scripts/ has only files from current active profile.

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.
/etc/sysconfig/networking/profiles/default: total 44 -rw-r--r--. 2 root root 271 Sep 3 22:00 hosts -rw-r--r--. 3 root root 315 Jun 30 13:39 ifcfg-br0 -rw-r--r--. 3 root root 248 Jun 30 13:39 ifcfg-br0:1 -rw-r--r--. 3 root root 248 Jun 30 13:39 ifcfg-br0:2 -rw-r--r--. 3 root root 248 Jun 30 13:39 ifcfg-br0:3 -rw-r--r--. 3 root root 248 Jun 30 13:39 ifcfg-br0:4 -rw-r--r--. 3 root root 248 Jun 30 13:39 ifcfg-br0:5 -rw-r--r--. 3 root root 211 Jun 30 13:39 ifcfg-br0:6 -rw-r--r--. 3 root root 211 Jun 30 13:39 ifcfg-br0:7 -rw-r--r--. 3 root root 229 Sep 4 01:06 ifcfg-eth0 -rw-r--r--. 1 root root 286 Sep 4 00:56 resolv.conf
Both C5 and C6 have "network" service able to create and switch to multiple profiles. For example, switching to profile "WiFiKuca" is done with:
"system-config-network-cmd -p WiFiKuca -a"
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/ .
