I don't know about profiles, and in a way I'm surprised my box works.

But this isn't rocket science.  You can read the scripts that run at 
boot -- in this case the networking one in /etc/rc.d/init.d.  You can 
see that it runs ifup on each interface (it just looks at the ifcfg-* 
files in the config dir).  You can also read the ifup script (it's a 
script, not a binary like Debian's).  So you can find the place that 
dhcpcd is run and what config file made that happen.

Change the right config and voila.

Removing DHCP so it doesn't try that isn't the answer.  The answer is to 
find out *why* it tries DHCP.  Heck, even something like:

find /etc/sysconfig/networking -type f | xargs grep -il dhcp

is better than removing (and later reinstalling?) things.  You could 
also use eth0, or maybe BOOTPROTO in place of dhcp in that find.

HTH,
