OK, I load the kernel from the JFS. I mount the root FS, which
is a JFS. I read the module "jfs.ko" from the JFS so that I can
mount the root FS, which is a JFS, so I can read the module "jfs.ko"
from the JFS so that I can mount the root FS, which is a JFS, so I
can read the module "jfs.ko" from the JFS so that I can mount the

Do you see the problem yet?

None of the Web Connections RS/6000 machines ran this OS/2 derived
code. I was under the impression that it was there for Linux
compatability. My impression is, layout or not, the original JFS
is much better code, overall.
