Changing between desktop environments is no longer a feature since
it's easier and more convenient to use only one environment, although
it's still certainly possible for the determined user.
As a side note, running a bootstrap.sh in a post-install environment is
significantly easier (and more practical) than trying to accomplish
every step before a reboot in the installation image. This separates
things like making partitions from the actual system.
Made dependency lists a bit more consistent and reverted some of the
Arch Linux wording since it felt a bit off. Even the official website
refers to Arch Linux as Arch from time to time.
