It will be a crapshoot. Depending on how far the two have diverged you may find that everything just works without any problems. (eg if you do a yum localinstall sl-release it will start pulling stuff from scientific linux and apps will work). However some stuff may end up just crashing without a rhyme or reason (well a good exercise for the student to track down why they are having problems with symbols and such). > Thanks, > > Vinod Gupta > Physics department > Princeton University -- Stephen J Smoogen.
