The embedded Linux nightmare - an epilogue

The embedded Linux nightmare - an epilogue

The big vendors do *not* limit themselves to backporting fixes into their enterprise kernels. Each of the five extant RHEL 4 kernels (original and updates 1 through 4) is quite different from the others. For example, the core device model code changed TWICE during updates between RHEL 4 kernels.

Backporting drivers to older kernels absolutely sucks as a way to spend your time because of changes like this, and worse, it feels like a waste of effort while you do it. Dispiriting stuff.
