If this is a concern, you should download the grub-efi-amd64-signed binary package with apt-get and extract the grubnet圆4.efi.signed binary instead of using the attached script.) (This does mean that an attacker could intercept your network traffic and replace the real grub圆4.efi with any other binary signed by a trusted key, such as a different OS. Note that it does *not* verify the grubnet圆4.efi.signed file at download time, but instead relies on the fact that the boot圆4.efi from the shim package will fail to pass control to grub圆4.efi if it is not a properly signed EFI binary. Ubuntu 13.10 or later is needed to run this script if your tftp server is deployed on an earlier version of Ubuntu or on a different OS, you will want to create an Ubuntu 13.10 chroot, run the script, and copy the result over to your server.

The uefi-netboot.sh script enables you to download and install all of these files securely from Ubuntu. The last of these files is optional, but makes it possible to provide the same high-quality graphical output for the grub menu when netbooting that you get when booting locally.
Unicode.pf2 from the grub-common package, installed as grub/fonts/unicode.pf2 under the tftp root. Grubnet圆4.efi.signed from the grub2 source package (and shipped in the grub-efi-amd64-signed binary package), installed as 'grub圆4.efi' under the tftp root from the shim-signed package, installed as boot圆4.efi under the tftp root Setting up the basic tftp root requires copying into place three main files: It is expected that future versions of MAAS will use the described method for hardware provisioning.
