Anything could start this process.

So you've already said where you should look.

If I had to guess you have a network init script which calls ifup.
Let us assume it's Debian's ifup so look in /etc/network/interfaces and check if 
you have set eth0 to dhcp.

IF so, I would remove this and set it to static or anything other than auto.

Then let the other init.d script start dhcpcd on all interfaces as it's 
currently doing.

OR do it the other way around - disable the init script that's starting dhcpcd 
in master mode and let ifup do it.
This is worse than the former, but if you only ever have one interface then it 
doesn't matter.
