I've done a 
# rm -rf *

...when sitting in /.  We've all done stupid things.

I agree.  I think that Yum should recognize that MySQL 4.1.11
supercedes MySQL 3.23.x and leave it alone -- however I believe that
what really drove Yum to do this was some ancilliary dependancy by a
KDE piece which named a MySQL 3.23.x component directly.  In my
opinion, Yum should have complained about the conflict and _refused_
to do anything.  I really don't know how this could be easilly
implemented, perhaps some form of --ignore-dependancy-conflicts (ie
--nodeps or --force).  The semantics would need to be worked out.

Oh, I still use it on the metric ton of other computers I administrate,
and this is the first time it has bitten me.
