Before the install script, i setup arch manually and added the gnome package that bringd DE and all the good Gnome stuff with it. it was then just the same as any other Gnome DE really. People taut the AUR, but OpenSUSE has same with their software.opensuse.org where packages maintained as experimental or community can be accessed (or by adding OPI). Since OpenSUSE had built in snapshotting, rollback and GUI admin (plus curation to do cleanups and maintemamce already OOTB) I uninstalled Arch. The ArchWiki though, that thing is a masterpiece
