Right, but that is not a property of the system, but a property of
the way ASDF uses system files to find the source files.

To wit: normal usage is to keep sources whereever, and symlink the
.asd to a directory in *CENTRAL-REGISTRY*, and let the symlink
resolution take care of finding the real source tree. :RESOLVE-SYMLINKS
breaks this (symlinks as part of the abstraction provided by ASDF).

As Christophe noted, the right thing may very well be to store
both the truename and the non-truename separately, so that you
can write an OUTPUT-FILES method that does the right thing.
