Well, once you can read the root options, you can easily enough make an initial effort to support it, even with the below caveats. You just need to use this value instead of the detected at build time one, i have not looked, but i can't imagine it is anything but trivial. > The fundamental design of yaird causes it to not be able to support > changing root at boot time.

Sure, but even with the same modules, it is still good to be allowed to override root, be it only to be able to boot into the system and rerun yaird or something. Imagine you moved the disk around on the same controler, or inserted a new disk and the ordering changed. Imagine too you used a tool like partimage to move the whole system to another partition of the same disk or of a similar machine. > * Only device files specifically needed to reach the default root > is created while in the pre-root boot stage. Indeed, but it would be trivial to create the command-line passed root instead of the build-time detected one. > I consider it a pretty damn good feature to have. But not essential.
