An initial (and quite naive) implementation was done for conf.d/ files but features do need it as well -- which became obvious during a casual inspection of distro/alt-workstation's target graph (which occured broken). The code is a messy hackery unfortunately, regexes used are fragile regarding e.g. [A-Z_] in target names. Read with care. NB: lib/ might need this too but it's rather stable and contains some special cases that would obstruct the regexes even more...a2897267
