yeah, that only works if you use redhat's kernel RPMs.

I got rid of that preferred **** in TL, and the rpm automatically links
/lib/modules/2.2.3 -> /lib/modules/2.2.3-1 or whatever.

You can probably use my 2.2.3 RPMs with Redhat, too, if your kernel is
acting up.  

PS - As of 3/29/99 I'm not officially an employee of PHT anymore.  I still
like TL, though, so I'll probably continue to recommend it to people with
problems, as is my prerogative.  I'm fireproof by now :)
