I understand so: if a port installs empty > directory, it may use @dirrmtry. And I'm asking what if a port > installs (creates) non-empty but shared directory?

If both port A and B install files in D and A and B don't depend on each other then both MUST use @dirrmtry D. If B depends on A and they both install files in D then neither should use @dirrmtry (B mustn't try to remove D because it didn't create it and A must @dirrm D since it has created it and B has already been deinstalled when A is pkg_delete'd). -- IOnut - Unregistered ;) FreeBSD "user" "Intellectual Property" is nowhere near as valuable as "Intellect" BOFH excuse #205: Quantum dynamics are affecting the transistors
