OK. So I finally got this all working (with the Debian Jessie RFS no less) by
exporting a file system for each target board. So overall directory structure
is something like this:

/home/bone/ <- 1st NFS root file system export
/home/bon

As of the January (or thereabouts) timeframe, u-boot has been patched so
that it now checks the SD card first then eMMC? (Evidence would strongly
suggest this is the case J ), irrespective of boot-switch .
