I'm trying to create a Live CD with a customized KDE Plasma desktop
(different widgets, panels, etc.). But whenever I try to overlay *any*
file from *~/.kde4/share/config* after the testdrive, I get an error on
the next build-and-boot: "Call to lnusertemp failed (temporary
directories full?). Check your installation."
Separately, I also tried copying files to */etc/kde4/share* and
overlaying those instead, but that doesn't seem to affect the user's
desktop on the next build-and-boot.
