It was kind of messy, I guess, because I had to also copy the full pathname whenever I was duplicating an FcPattern (and this happens a number of times). It would be nice if I could think of a simpler solution, but this seems to work. So, we have basenames in caches; these basenames are relative to the cache file's (conceptual) location. (Even if we stuff them all in /var, we know what directory the cache file belongs to.) So you can move your directories all around the drive, or mount them in different places, and things should continue working. pat
