# change-settings used to copy a whole dnf.conf over the machine's own, and
# that file set defaultyes=True -- so every `dnf remove`, for every user,
# treated a bare Enter as confirmation. The installer no longer ships the
# file; this repairs the machines that already received it. Only the one
# behavior key is touched: the performance keys it carried are harmless and
# now applied additively by change-settings.
