They are ARM64 Cavium ThunderX systems in 1U Gigabyte chassis.

These machines are configured in DHCP to receive /var/lib/tftpboot/aarch64/grubaa64.efi from the Cobbler host when PXE booting. This brings up the menu I manually created in /var/lib/tftpboot/aarch64/grub.cfg.

Hopefully we won't need this but I thought it was worth documenting since we didn't know the logins for the Xenial installation that came shipped with the systems.

let system boot and get to PXE grub menu
Press C for grub command prompt

Use `ls` to figure out where the boot partition is.  (e.g., ls (hd0,gpt2)/)

grub> linux (hd0,gpt2)/boot/vmlinuz root=/dev/sda2 init=/bin/sh
grub> initrd (hd0,gpt2)/boot/initrd.img
grub> boot

# mount -o remount,rw /
# passwd root

# /sbin/reboot -f
