	Can I ask what may be an obvious question, but what about having the 
postinstall script that the rpm runs do pathname substitution on a template
config file?  
	i.e. the RPM contains a "config.template", which contains several 
%INST_PATH% tokens, rather than the actual installation path.  Then, as part
of the postinstall process (where daemons would be restarted, etc), you just
do a sed s~%INST_PATH%~/actual/installation/path~g on the config.template, 
writing the output to the actual config file?
