Script swiss (army knife)
Designed to make different workflows for the installation process. Which is controlled by the argument --mode
mode full guides the full process of installation
mode only_hd only proceeds to the creation of the disk infraestructure (partition, mount points, encryption)
mode only_os processes only the installation of Archlinux and software at --mountpoint (or /mnt/archinstall)
mode minimal (still not implemented)
mode lineal. Instead of a menu, shows a sequence of selection screens (eq. to the old mode for guided.py)
When using the argument --advanced. an additional menu for several special parameters needed during installation appears
This script respects the --dry_run argument
