Bug#403776: closed by Sune Vuorela <email@example.com> (Re: Bug#403776: kdm uses only theme)
I found this in /etc/init.d/kdm :
This means the configuration files must be placed in /var/run/kdm (I
tried and it worked as I wanted), I think this is a very bad thing
according to http://www.pathname.com/fhs/pub/fhs-2.3.html#VARRUNRUNTIMEVARIABLEDATA
(which is supposed to be a kind of standard)
Maybe there is a very good reason I ignore but else this seems grave !
