I think the severity of this bug should really be set to critical per debian's definitions (breaks unrelated software on the system)
In buster this package worked fine with gnome, in bullseye it breaks other packages. This includes at lease uuidd-runtime upower and parts of gnome (gnome settings crashes/fails to start/freezes if upower did not start). The only error messages talk about lack of disk space which is not accurate. Although the fix may be simple, it's pretty frustrating and difficult to understand. Users like me will assume Debian has messed up gnome by not testing things properly. Can i request one or more of - something in README.Debian listing packages broken by this package and documenting how to re-enable user namespaces - splitting setting user.max_user_namespaces into a separate package which conflicts: uuid-runtime, upower (and anything else affected) - put the setting of user.max_user_namespaces=0 into /etc so it's easier to override - have something in postinst that warns the user if upower and uuidd are installed Happy to help write documentation if that would help.
