kernel
======

This is a rather complex Bundle for the Linux kernel from a system with
a history of complexity. There are two kernel versions present on the
systems at all times (the current and the previous), so the package
names all contain versioning information. This includes kernel-specific
modules for various specialties - ``gm`` for Myrinet boards, ``gpfs``
and ``pvfs`` for storage clients, and ``nvidia`` modules for machines
with Nvidia cards. Note that only the ``ia32`` machines have Nvidia
cards in them, and thus those entries only exist in that section.

It is easy to see that there is duplication of effort between the
two architectures - both have the same ``linux`` package entry names,
for example. This Bundle could be arranged in many different ways,
some of which might be better than this one. Feel free to hack as needed.
