[gPXE] gpxe booting with NFS

[DiP]

Hi all

I`m confusing to search how to get gpxe compiled with NFS support
Is there any written directions?
rom-o-matic do not generates images with NFS support, or I didn`t found where
to switch that on.

For now I have reduced netboot with tftp switched off, only
http+nfs root. I wonder to make it to use only NFS at all for that.

Thank for advance
