It works for me on four servers I recently set up if I put it into /EFI/NetBSD 
on the ESP. It also, for reasons unknown to me, works on one other identical 
server I set up earlier (the prototype for the others) if put into the root 
of the ESP, but that doesn't work on the four others. I didn't find out why.
