`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.
