not the parent one, but the "childs" one. so you'd say READONLY_ROOT="/:DEPEND" in your $ROOT. so when merging to $ROOT, '/' will be searched for DEPENDs. er... you can remove all hunks for vartree.py and remove the argument "kill_eprefix" from all calls to vartree (should be one only i guess). sorry - forgot about that.
