It's possible that it'll hang on some of the files in /proc if it gets to that directory before /sys, but that's largely a matter of chance. > The above command first will > get to removing /dev, and it will delete /dev/sda1 or whichever device / > filesystem lives on.

Access to your filesystems doesn't depend on the device nodes after they're mounted. You can remove all of the nodes in /dev, and your filesystems remain available. Spin up a VM and test it. I promise, it works. > And portion of /dev - whatever alphabetically is before > root filesystem device. rm doesn't process files in alphabetical order. It processes them in directory order, which is unpredictable.
