*nod*  Its configurable for this purpose.  My insitution has to have
OpenAFS working, but in the general case I agree.  I think its set to
on on yum-utils right now, I'll make sure it defaults to off.

are installed only.  The only time a kmod is removed is when there is an
updated version for a kernel that already has an older version of that
kmod installed for it.

Not yet.  But I'm not done yet.
