Can you clarify what you mean by the above?

Likewise, can you clarify the above?

I'm getting an error when loading a gzip(1)'d kernel...

	don't know how to load module '/kernels/GENERIC-i386-9.0.gz'

So I figure, maybe it doesn't like the '.gz' suffix. No go, same error.

Or maybe there's a special syntax to loading a gzip'd kernel? If so, that's unfortunate as no special syntax is required to execute kgzip'd kernels.

Also, kgzip produces smaller binaries than gzip when used on kernel. I'd like to see kgzip(1) functionality restored (again, it worked fine in RELENG_8).
