Yup, I find that it is just much cleaner and easier since you are building a
kernel for a very static piece of hardware (how often do you change your
master node on a cluster?) it is much easier to just build a lean kernel
that has only what you need and compile it all in, rather than going through
the trouble of complicated module loading in grub.

I also network boot my diskless nodes, so yes it does take a little longer
to boot with a heavier kernel which may have some hardware support in it
that a slave node does not need, but I consider it pretty negligible.
