Calamares is a distro- and desktop-agnostic installer. Developed as an installer for Linux distributions -- dozens of them -- it is modular and highly configurable. It can be used as an installer for FreeBSD- based distributions as well, though it needs extensive configuration (which is not included in the port yet). Upstream tracking of what still needs tweaking can be found at https://github.com/calamares/calamares/issues/1795 WWW: https://calamares.io/
