In general port X depend from port Y ==> X is not valid without Y. But exists many cases, in which port X particulary depending from Y. It means, that some subparts of X is not valid without Y. for example: simpack particulary depend from tk4.{1,2} (as it have sdsmt) noweb particulary depend from teTeX or tex-3.1415 (as it have noweb.sty: LaTeX style) gnats particulary depend from emacs/xemacs (as he have send-pr.el) I want introduse that: *ports X linkable with port Y, if X have additional feautures, which work if Y is installed* I want to have such ports system, which allow install X, than install Y. How to do it: let we have structure, such as windows registry, wher we holds "port-lincable" ports and actions. Example: TeX CONCEPT : STYLE_DIRECTORY ACTIONS : LINK_STYLE = ln $1 $STYLEDIRECTORY teTEX CONCEPT : STYLE_DIRECTORY=/usr/ports/teTeX/tex/texfmts SHELL_VARIABLES: TETEXROOT=/usr/ports/teTeX. ACTIONS : LINK_STYLE=action(TEX,LINK_STILE);tetexhash tex-3.14.25 ......... in teTeX port MAKEFILE: or may be in teTeX/pkg/ports-registry PORTS_REGISTRY_TOP_KEY=TeX PORTS_REGISTRY_CONCEPTS="STYLE_DIRECTORY=${PREFIX}/teTeX/tex/texfmts" PORTS_REGISTRY_SHELL_VARIABLES="TETEXROOT=${PREFIX}/teTeX" PORTS_REGISTRY_ACTIONS="LINK_STYLE=action(TeX,LINK_STYLE);tetexhash" in noweb port Makefile: (or pkg/ports-registry) PORTS_REGISTRY_LINK_DEPEND="action(TEX,LINK_STYLE) ${PREFIX}/noweb.sty" And in /etc/daily we can run programm, which see: if new ports added ? if they have ACTIONS ? if we have ports with ACTIONS_LINK_DEPEND from it ? do this actions. 2. During boot, we can read shell variables from ports-registry to initial shell. (Many ports want to have it's own variables.) In principle, I can start to write such application, which can work independed from other system code.
