[oe-commits] org.oe.dev SlugOS 5 - replace "mount -U" with "mount UUID=" which works with both mount

[mwester commit]

SlugOS 5 - replace "mount -U" with "mount UUID=" which works with both mount
and busybox mount; also update boot/disk script to ensure that some key
devices exist in the new /dev which will enable booting to a virgin nfsroot.
