Need some help NFS booting a mounted Ubuntu 16.04 mini.iso (both UEFI and BIOS)

[maggreg]

This config working for me (desktop live), efi and legacy, 16.04 and 16.10:

Code:

:ubuntu
set args1 vga=791 boot=casper toram
set args2 netboot=nfs nfsroot=${next-server}:/data/tftpboot/ubuntu root=/dev/nfs
kernel nfs://${next-server}/data/tftpboot/ubuntu/casper/vmlinuz.efi ||
initrd nfs://${next-server}/data/tftpboot/ubuntu/casper/initrd.lz ||
imgargs vmlinuz.efi initrd=initrd.lz ${args1} ${args2}
imgstat
boot || read void
goto start

And mini:

Code:

:ubuntumini
kernel nfs://${next-server}/data/tftpboot/ubuntumini/linux ||
initrd nfs://${next-server}/data/tftpboot/ubuntumini/initrd.gz ||
imgargs linux initrd=initrd.gz vga=791 toram
imgstat
boot || read void
goto start

My "exports" for this share:

Code:

"/data/tftpboot" *(insecure,insecure_locks,root_squash,anongid=99,anonuid=99,no_subtree_check,rw,​async)
