That guess is ill-founded. Red Hat has been very, very good about
using GPL to publish their tools, especially kernels, and publishing
their installers. And I've personally various RHEL, CentOS, and
Scientific Linux systems on large environments with half a dozen
attached disks and never encountered what you're encountering. But I
do not partition anything but the "/" disk at installation time, i
always do the others later.
