Details:

if "root" is on "(tftp)", ls wont work.

Boot grub2 from network. Then "c" for a commandline.
echo ${prefix}
-> (tftp,172.18.8.1)grub

ls ${prefix}
->

wont produce any output.
I've awaited to find something like:
-> bgrnd
-> chbg.cfg
-> chlg.cfg
-> fonts
-> grub.cfg
-> i386-pc
-> locale

or, if tftp where not capable of directory listings an error message like:
-> Impossible

And a set return code to have it not fail silently. If used in grub scripts.
