	`Installer()` is the wrapper for most basic installation steps.
	It also wraps :py:func:`~archinstall.Installer.pacstrap` among other things.

	:param partition: Requires a partition as the first argument, this is
		so that the installer can mount to `mountpoint` and strap packages there.
	:type partition: class:`archinstall.Partition`

	:param boot_partition: There's two reasons for needing a boot partition argument,
		The first being so that `mkinitcpio` can place the `vmlinuz` kernel at the right place
		during the `pacstrap` or `linux` and the base packages for a minimal installation.
		The second being when :py:func:`~archinstall.Installer.add_bootloader` is called,
		A `boot_partition` must be known to the installer before this is called.
	:type boot_partition: class:`archinstall.Partition`

	:param profile: A profile to install, this is optional and can be called later manually.
		This just simplifies the process by not having to call :py:func:`~archinstall.Installer.install_profile` later on.
	:type profile: str, optional

	:param hostname: The given /etc/hostname for the machine.
