I wanted to test Qt 4.7.9999 on an ~arch system, but the compilation of qt-gui fails. Before emerging, I did quickpkg the old qt packages. However, I now can't bring those backups back: emerge -a1K qt-core qt-script qt-dbus * Sanity check to keep you from breaking your system: * Downgrading Qt is completely unsupported and will break your system! * ERROR: x11-libs/qt-core-4.7.3 failed (setup phase): * aborting to save your system However, this is an outright phail. It doesn't save the system, it botches it. It can't go back nor forward. "Saving the system" would mean I should be able to undo the emerge. Qt is *not* glibc. It won't destroy your system since you still access to it from the terminal or from another DE (like Gnome or XFCE.) Reproducible: Always
Oopsy, the I_KNOW_WHAT_I_AM_DOING env var does allow for overriding and works OK. Sorry for the noise.
