Save your settings, and run commands like this to install a single set to your system:

- save your settings first
# tar -cvJpf etc.tar.xz /etc

# tar -Jxvpf base.tar.xz -C /
- do the same with other sets except for etc and xetc

# etcupdate -av -s etc.tar.xz -s xetc.tar.xz

# postinstall fix

Then reboot to be on the safe side.
