Suppose package P installs file F in directory S, but S is really a symbolic link to directory D. Running epm -qf D/F won't work: % epm -qf D/F file D/F is not owned by any package It'd be neat if there was a "follow symbolic links" commandline flag. For each filename the package installed, epm could see if there are any symbolic links in that filename's path which would resolve it to the path specified on the commandline. This would be particularly nice on amd64, since e.g. /usr/X11R6/lib64 => /usr/X11R6/lib and /usr/X11R6/lib32 => /emul/linux/x86/usr/X11R6/lib32. Thanks for your consideration!
Aron, I'll make a patch for this and send it to you for consideration. Thanks for the great and extremely helpful tool!
Created attachment 45352 [details, diff] patch to add -L (follow symlinks) option (diff -u format) Aron, Here's a start, at least. This is one of my first patch contributions so please bear with me as I don't really know the etiquette. This patch adds the -L commandline flag to dereference symbolc links when searching with -qf. It uses some GPL'd dereferencing code I found online (see source attribution in code). It is also rather slow, I'm afraid. But perhaps someone will find it useful. I disclaim any copyright or IP interest in this code. Thanks again!
Forgot to mention, the patch is against the epm-0.8.8 ebuild.
Created attachment 45354 [details, diff] UPDATED patch (halves the performance penalty) This version halves the performance penalty by only running dereference_links() once on the original filename. It was foolishly in the inner search loop before.
Reassigning to maintainer-needed since package was not being maintained by anyone in tools-portage herd.
I'm not sure if this desirable. The epm interface was built to be very similar to rpm and in |rpm --help| (on an OpenSUSE machine) I cannot see any such -L switch. I would also like to see a real-life example of where a package installs into a dir that's a symbolic link. I would call that a bug of that package...

I would call that a bug of that package... Have you think in maintaining this via a proxy? http://www.gentoo.org/proj/en/qa/proxy-maintainers/index.xml
This is fixed in app-portage/epm-1.40. It automatically resolves the symlinks so the correct package is printed.
