actually, those appear to be links to the same files...

# ls -il /etc/sysconfig/network-scripts/ifcfg-eth0
2524900 -rw-r--r--  3 root root   162 Nov 29  2007 ifcfg-eth0
# ls -il /etc/sysconfig/networking/profiles/default/ifcfg-eth0
2524900 -rw-r--r--  3 root root 162 Nov 29  2007 
/etc/sysconfig/networking/profiles/default/ifcfg-eth0
# ls -il /etc/sysconfig/networking/devices/ifcfg-eth0
2524900 -rw-r--r--  3 root root 162 Nov 29  2007 
/etc/sysconfig/networking/devices/ifcfg-eth0


note the inode# is the same on all three.

sysconfig (8) forces the system to run /etc/rc.d/rc.sysinit upon 
reboot.  you might take a look at what that script is doing (a fair bit, 
actually).
