			== Partitioning ==

			The goal is to have a small disk file for the MBR and /boot, and a larger raw filesystem in
			an LVM Logical Volume. We don't want the LV to be partitioned because this makes it harder to
			resize, mount, etc.

			Now create a partition table in the smallest disk (256MB) and create a single partition in it.
			Format this partition as ext4, labeled "boot" and mounted as /boot.

			The installer won't let you format the entire disk as a filesystem, so go ahead and partition
			the 10GB disk too, then create a primary partition in it and format it as ext4, mounted as /
			and labeled "template-xenial" ('''"template-focal-root" would exceed the ext4 limit''').

			And yes.. just in case you're wondering. We don't use swap partitions.

			We'll have to fix the disk later.

			'''Obs''': ''format=raw'' is mandatory, otherwise qcow2 format will be used by default.
			''raw'' format allows us to easily create device mappings for the image.


			The new VM will boot into the installer. Answer all questions with the defaults, except:

			# Hostname: template-focal
			# Mirror: enter information manually
			# Mirror hostname: ubuntu.media.mit.edu
			# (create your user with a strong password and no encrypted home)
			# Partitioning: manual (see Partitioning below)
			# Automatically install security updates
			# Software selection:
			#* Basic Ubuntu Server
			#* OpenSSH server
			# GRUB: let the installer setup grub on /dev/vba (which contains /boot)
