toward the end of a class on friday, just for fun, i showed the students how to install git, clone the latest kernel source, and build and install a new kernel. since it was getting close to end of day, i wanted to keep it simple and directed them to just "make defconfig" to see what would happen.
the configuration and build of the kernel and modules worked fine, they installed the kernel and modules, then rebooted but the new kernel panicked almost immediately, apparently whining that it couldn't mount the root filesystem. since they were all running LVM-based systems, i assumed that perhaps we needed to explicitly add LVM support during the config step.

again, anyone else done this? should it work? i'll try this later today as soon as i have access to my test system again.
You can find the answer here :-)
