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.
