            Bug ID: 1174734
           Summary: grub can't be insntalled like that for UEFI network
                    installation

Description of problem:

Instructions in page:

https://docs.fedoraproject.org/en-US/Fedora/20/html/Installation_Guide/s1-netboot-pxe-config-efi.html

don't work.  grubx64.efi is not able to boot through the network.  What you
need is something more similar to:

grub2-mknetdir --net-directory /var/lib/tftpboot/uefi/ --subdir x64-efi

and change:

     filename "pxelinux/bootx64.efi";

to (with the paths that I showed):

     filename "uefi/x64-efi/core.efi"


Configuration file is searched as:


file /mnt/mirror/tftp/efi-x64/grub.cfg-01-3c-97-0e-da-28-fb not found
file /mnt/mirror/tftp/efi-x64/grub.cfg-C0A80ACB not found
file /mnt/mirror/tftp/efi-x64/grub.cfg-C0A80AC not found
file /mnt/mirror/tftp/efi-x64/grub.cfg-C0A80A not found
file /mnt/mirror/tftp/efi-x64/grub.cfg-C0A80 not found
file /mnt/mirror/tftp/efi-x64/grub.cfg-C0A8 not found
file /mnt/mirror/tftp/efi-x64/grub.cfg-C0A not found
file /mnt/mirror/tftp/efi-x64/grub.cfg-C0 not found
file /mnt/mirror/tftp/efi-x64/grub.cfg-C not found
file /mnt/mirror/tftp/efi-x64/grub.cfg not found


(change /mnt/mirror/tftp/ for whatever is your tftpboot)

And format of the file is something like:

set timeout=1

menuentry 'Fedora 21' {
  linuxefi fedora/21/x86_64/vmlinuz 
ks=http://mirror.mitica/kickstart/x86_64-21-standalone.cfg ksdevice=link
  initrdefi fedora/21/x86_64/initrd.img
}

And I haven't found any use for efidefault, not being able to use pxelinux from
inside grub (in efi systems).

If you have any questions, please, let me know.

Thanks, Juan.

PD.  I use dnsmasq instead of dhcp-server, but it shouldn't be a different for
this.
