I prefer to have a single configuration file, so I don't have to maintain different configuration files in parallel.

Referring to section 7.1 of the ASDF user manual, none of the options described there seem to work with RMCL, as far as I can tell, because ASDF 2 seems to make strong assumptions about what physical pathnames are supposed to look like (basically, Unixy), and these assumptions simply don't hold at all for RMCL.

Maybe this is where I'm misunderstanding some of the internal workings of ASDF 2. But I am seeing hard-coded physical pathnames, such as ".config/common-lisp/", all of over the place in asdf.lisp. 

What am I missing?

OK, good.

Well, so far it only worked for me using the hack I described. I guess I'm doing something wrong...
