Why should new function break old/current code ???. Look at the way Media Manager was introduced - bring it in as new function. As for the IPL-time issue, just needs to be specified as a limitation - no FBA for resvol (whatever). Again, just look at how zFS was handled. It wasn't until 1.7 that the root could be zFS - we all managed to survive. > Why should IBM do this? It won't make them any money that I can see.
