I'm NOT the authority here, but AFAIK, Htree is presently available only as a patch for 2.4 kernels (which includes RH8). I think that Htree was still beta code at the time RH8 was frozen (and may still be, from RedHat's perspective). I do not have the impression that the Htree patch has been applied in any standard RedHat kernels or kernel updates. I hope I am wrong, and that someone will enlighten me. A.
