-Subject: [PATCH] main: Implement --prefix option to override install path
-
-Implement a --prefix option that can be used to override platbase
-and base when expanding the paths from install scheme.  This can be used
-to install paths to a layout using another prefix than the one used
-to run installer.
-
-Gentoo use case for this is running installer inside a venv to prepare
-installation images for the real system.  The nixOS maintainers have
-also indicated interest in this feature.
