I'd say in the same way they would be expected to modify the RedHat
/etc/rdma/rdma.conf file. I copied the defaults from that file, which
was to autoload target drivers.

I agree with you, they probably don't make sense to be defaulted on.
Ideally their respective supporting packages or kernel would ensure
the modules autoload if someone is working with RDMA... I know nothing
about the target infrastructure - can you see a way to do that?

Thanks,
Jason
