[gentoo-catalyst] changing genkernel's configuration files as invoked by Catalyst

[Joshua Hoblitt]

Hi Folks,

I'd like add the "arcmsr" driver to the set of SCSI modules included in
the initrd image generated by genkernel when run by catalyst.  I
understand what genkernel files need to be modified to accomplish this
but I'm not sure how to do this under catalyst.  Do I need to provide a
portage overlay to catalyst or is there perhaps some magic variable that
can be set to point to genkernels config files?

Thanks,

-J
