My plan is to re-purpose the HDD to pure storage and remove Mac OSX.
Reading in another thread, Rod recommended that one shouldn't bother trying to move the EFI partition but to keep it in its original location. It's only 200M so that's fine.
As for CentOS I have different kernel versions and I need to be able to explicitly set which one is the default.
Reading in a yet another thread, I'm supposed to set the default_selection item in refind.conf. I'm also supposed to find this under /boot/efi/EFI/refind.
However, in CentOS, that directory doesn't exist. I've also done a system-wide search - refind.conf is nowhere to be found.
So, I'm assuming it's located somewhere on the HDD hosting Mac OS (sda).
Assuming, I'm correct - on what partition and where can I find it?
Or is there a way of doing it from the sdb disk?

I have a Mac mini (2011) with two drives:
500GB HDD (sda) running Mac OS Sierra
