You can, and we have on two RHES3 production machines -- because of all the interdependancies on the shared libs, it's easier to simply install all the client RPMs, untarball the 4.x server into a location and run the install scripts, etc. It will read your /etc/my.cnf and make the libs over in /var/lib/mysql and so forth - a few minor mods to the init.d mysql script and you're done. This mixed mode has been running like a champ, no problems. -te -- Troy Engel | Systems Engineer Fluid, Inc | http://www.fluid.com
