Despite the barbs shot against XFS by that fellow from gentoo, I have
never had a problem with XFS. But I use Linux on my desktop PeeCee and
that probably obviates some of the problems of XFS. My servers run
Solaris and OpenBSD. In fact, the machine from which this article arises
is a Sun Ultra 1 running Solaris 9.

So your statement "?? Modutils has no interesting bugs. Never has had,
as far as I know." requires correction?

The utilities are probably stable at this point. But the use of -any-
otherwise unrequired utility carries risk with it.

Air is indeed deadly to human life for some people - those who dive in
deep waters and return too swiftly to the surface.

Naming a NIC which uses a different architecture with the same
nomenclature as the previous generation is not innocent. It is mindful of
the behavior of LinkSys with their LNE-100TX series of 4 separate chips
and god_only_knows how many different chips sold by SMC.

Use supported hardware and forget about having to modprobe some
experimental module. You might enjoy fixing such things but most people
simply do not have that capabilty.

Do you think the OP now knows where to find bzImage?
