dev-util/git installs 90 copies of the same binary. Each copy is 963080 bytes large on my system, so that adds up to a rather large waste of space. There are a few other duplicated files as well. $ du -hc $(qlist git) | tail -n1 92M total All of the files within each set of duplicates SHOULD be references to a single copy, either by symbolic links or by hard links. Here is a list of the duplicates and the number of copies of each: $ md5sum $(qlist git) | sort | uniq -cdw32 2 19209bb2b00f0ecd80a9def73bb79234 /usr/bin/git-upload-pack 2

I had that problem too - and I was wrong. Those are not copies of the same binary - those are hardlinks (at least most of those are). What's more those are planned to go away in one of the future releases of git (though it's not told exactly when). Check this with 'du' and 'du -l' on 'duplicates' lists.

However, they *are* hard links in the "image" staging area beneath /var/tmp/portage prior to being merged. Methinks Portage is not preserving the hardlinkedness when merging onto the live file system. So this might not be a git-specific problem but rather a Portage problem. # ebuild /usr/portage/dev-util/git/git-1.6.0.4.ebuild install > /dev/null
The following function could be called in the git ebuild to convert the hard links into symbolic links that Portage would preserve when merging: make_symlinks() { md5sum $(find "${D}"/usr/libexec/git-core -type f) | fgrep $(md5sum "${D}"/usr/bin/git | cut -c-32) | cut -c35- | fgrep -v '/usr/bin/git' | while read dup ; do ln -sfv ../../bin/git "${dup}" done }

Begging your pardon, but the fix mentioned in bug #170066 is not included in the ebuild for git-1.6.0.4. Thus, the problem persists.
Hey, that's odd...
This is a Portage "feature". Feel free to reassign the bug to them though. - ferdy
