Renaming configuration files

[Rivo Laks]

Hi

I need to rename a configuration file. Usually it should be doable with 
kconf_update, but I need the new name to include the computer's current 
hostname. And as far as I can see, kconf_update doesn't let me have e.g. an 
expression as the new filename.
So, any ideas on how to do this, preferably with kconf_update so that it 
wouldn't be necessary to put this logic into the application code?

Some background info: I'm trying to fix bug #200157. The problem is that a 
single config file is used when logging into a same user account from multiple 
computers. This results in Phonon warning the user about missing soundcards. 
I'm now trying to rename the config file to "phonondevices-${HOSTNAME}rc" 
instead of just "phonondevicesrc", so that device info of different computers 
would be stored separately.
