For several +filesystems barebox can automatically append a suitable root= option +to the Kernel command line. This is done when ``global.bootm.appendroot`` +is true. How the root= option is appended depends on the device type +and filesystem the kernel is booted from. For disk like devices (SD/MMC, +ATA) the partition UUID will be used, the root= option will be something +like ``root=PARTUUID=deadbeef-1``. For UBIFS fileystems it will be +``root=ubi0:volname ubi.mtd=mtdpartname rootfstype=ubifs``. NFS +filesystems will result in ``root=/dev/nfs nfsroot=ip:/path/to/nfsroot,v3,tcp``. +The ``v3,tcp`` part is configurable in ``global.linux.rootnfsopts``.
