Agreed. Downgrading some individual packages to stable (e.g. due to a bug) is often fine (manual checks/fixes might be needed), but I would never downgrade a full system. If one goal was to keep some configuration changes in /etc, then backup /etc, but do not restore it. Just do a recursive diff and see what may need to be changed again. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
