There exists currently no way to view the kernel root option that barebox would generate when instructed to via global.bootm.root_dev, but without actually mounting the file system.
Add a new -K option that can print this. This can be useful in scripts that want to fixup the root line, so it's interpreted by the rdinit, but not by the kernel.
