I'm interested to help contribute to a boot speed document, and I
suspect some others at Red Hat are interested as well. Personally,
I would prefer to have a section in the kernel documentation over a
Wiki. Besides arch-specific recommendations, we can also contribute
some boot speed improvement techniques that we've done that are
specific to RT.

In addition to the recommended configs, I think it would also be
beneficial to list some upstream patches that improve boot speed along
with the kernel version it was introduced in.
