That said, I regret that we have accidentally broke innocent uses of *load-truename*.
But maybe I can make a FAQ entry for this case.
There is nothing innocent about assuming that compiled file are close to the source files, or that the source files are available at runtime, what more at the same location as at compile-time. Unless may if you're using Nix.
I've avoided getting into this discussion, but I feel I need to ask: why use *load-truename* instead of *load-pathname*?
*load-truename* goes through symbolic links (even though the ANS says nothing about it, this is the behavior of implementations I know of) and that is almost always the wrong thing. GNU make doesn't do it, I don't see why ASDF should do it. A build system should never itself follow symlinks, because it defeats systems that have been in place for 30+ years: linked directories of binary files linking to a single source directory.
