This patch adds support for the RPMPOPTFILE and RPMPOPTDIR environment variables to set default locations for popt.
Created attachment 10682 [details] popt env. var patch
Using the environment to locate config files, particularly for popt, is dangerous, as popt config can too easily be used to remap executables and command line options onto trojan horses for example. The underlying idea(s)/need(s) are sound, so I'm gonna mark DEFERRED, I just don't believe that the envirornment is necessarily the best implementation.
