Copy a .config over and run make oldconfig Yes, there could be incompatibilities. This might happen once every few years when you do an upgrade over 10 version numbers. But that can be fixed. Not doing it this way means a very high likelyhood of the machine not booting with every single upgrade, plus the huge amount of work it takes to go through everything in menuconfig. The choices are simple, - low risk of occasional breakage - high risk of frequent breakage -- Alan McKinnnon alan.mckinnon@gmail.com
