Comment 5 for bug 284210

If I want to create something like that by hand, which files & directories I should copy to make sure it's operational?

The reason why I want to do it is that recent kernel updates are just incremental updates to the same kernel. I personall experienced a problem when latest update broke the WiFi support (it was fortunately resolved in couple hours, but it was really troublesome)

I know it's devel relase so things like that are normal, that's why I want to protect myself from that in the future,
My laptop doesn't have cd-rom and floppy drives, so if kernel would make system unbootable, I'll have to play with PXE again :(
