Yes, the files in .../var/macports/software is what's called an image, for all the low-level details see the guide: <http://guide.macports.org/#internals.images> Basically a given port is first installed in this directory, then when it is activated hard links are created in just ${prefix} to the stuff in .../var/macports/software so it can be visible. > + Is there a way to "clean" duplicates? Since it uses hardlinks it shouldn't be really taking up twice the amount of diskspace, but of course it does create another link for every file. The more common disk space user is having multiple installs of a port when you only need the current (happens with 'port upgrade outdated' which doesn't uninstall the older version). To clean those you can use 'sudo port uninstall inactive' to remove those (assuming all ports you have which are inactive are not wanted). Long-term, the way images are handled should be changing by not doing the install-then-hardlink style, see ticket #19458: <http://trac.macports.org/ticket/19458> Bryan > > -- > Bill Muench > Santa Cruz, California _______________________________________________ macports-users mailing list macports-users@lists.macosforge.org http://lists.macosforge.org/mailman/listinfo.cgi/macports-users
