Yeah, after re-reading the wording it seems that is the case. What about for pkg_deinstall (part of portupgrade)? According to its man page, it has two options, --recursive (-r) and --upward-recursive (-R). Maybe it's just a little bit late, but what /exactly/ is the difference? It sounds like the --upward-recursive option would be better called --downward-recursive, since it will remove the ports/packages "below" it. So, if that is the case, would pkg_deinstall -R pkgA remove pkgB or not? -- To send me a personal email, please place [personal] in the Subject line.
