I grepped the entire Trinity source tree and found only a few instances of Trinity using $HOME/.kderc.

kiosktool
tdebase
tdelibs
tde-i18n (all kdesktop.po files)

I grepped some of the KDE4 sources. This file remains in use in KDE4.

I don't know whether the format of this file is shareable by both desktops. To avoid potential conflicts, I recommend renaming to $HOME/.tderc.

I would update the migratekde3 script too.

There are references in the Trinity code to /etc/kderc. This file is not related to $HOME/.kderc, but is still used in KDE4. Seems then /etc/kderc should be renamed to /etc/tderc. There is a /etc/kde4rc. Perhaps /etc/kderc is retained in KDE4 for historical purposes.

I think that moving $HOME/.kderc to $TDEHOME/share/config/kderc and not being hidden as a dot file makes sense.

Any objections to this renaming? Speak now or forever hold your peace. :)

Thanks.
