Anything needed for early boot is already in /. The problem is that udev is trying to run all its rules at that early stage, when it should not. This currently causes some actions to fail because /usr is not mounted yet. The solution is not to mount /usr early, because that only deals with one case, but to make sure that udev does not run actions until the full system is available. This has been stated many times by several people in the previous threads. > So yeah, the udev rules can execute arbitrary code, but the should not > run stupid code. There is a difference.

Again? It's already been covered many times before. You expect people to blindly accept your POV that an initramfs is a good thing, yet refuse to see the circumstances where others believe it is not. For one thing, implementing this in a stable, running system without interruption is a non-trivial task. -- Neil Bothwick Where do forest rangers go to "get away from it all?"
