I expect it does. My question boils down to: Why isn't the answer to "Where is PREFIX?" just "install_base does the same thing", which is correct in 99% of cases that anyone cares about. Instead there seems to be always a long discussion about how bad PREFIX is, that never actually gets to the point.
NB: I have most likely not read all existing discussions on the subject, so this is just a synopsis of those on PM that I've seen.
