I just upgraded to kdebase-2.1-6 and noticed that my /usr/share/config/kdmrc file was gone. Previous release did an rpmsave on this.
Fixed in 2.1-8. The problem was that we tried to replace the /usr/share/config directory with a symlink to /etc/kde (which would make more sense FHS-wise), but rpm doesn't handle this case well, so we've reverted the change.
