What is the use /etc/sysconfig/networking/profiles/default/* files ?

Issue

• Should /etc/sysconfig/network and /etc/sysconfig/networking/profiles/network be hardlinks?
• Should system-config-network insert "NETWORKING_IPV6=no" in the networking files if IPV6 is not selected in
  system-config-network -> Edit eth0 -> General Tab.
• Why shouldn't same configuration details be available in both network files? Don't we want the profile to reproduce our network configuration?

• If we remove both files and run system-config-network it makes two separate files. Neither indicates that we do not use IPV6, which is not selected in the configuration.

• /etc/sysconfig/network
