Then you missed uiop:ensure-absolute-pathname, and/or the
:ensure-absolute option to ensure-pathname (and, by extension,
parse-unix-namestring).

It's there because indeed ASDF 3 uses it, precisely to prevent
situations like the one you mention.

It's in uiop/pathname, but if you might in many cases suppose
#'uiop/os:getcwd as its :default.

Remarkably, uiop is now 40% larger than asdf/defsystem, and over eight
times larger than the original ASDF 1.85... that's the price of being
portable and robust.
