I still fail to understand the bikeshedding here - you really don't need a git checkout to get something akin to a changelog. Use the github API directly...
The following 1-liner could be trivially productised (maybe even parse $PWD to set the path argument...) curl https://api.github.com/repos/gentoo/gentoo/commits?path=app-admin/eselect | perl -MJSON -e 'foreach $i (@{decode_json(join("",@lines=<STDIN>))}) { print "$i->{commit}->{author}->{name} - $i->{commit}->{author}->{date}\n\n $i->{commit}->{message}\n"; }' Yeah - it's not quite as pretty as our current Changelog, but date, author/committer, commit-msg etc. are all there and you can filter by path just the same as you would with native git log... You could parse the local $PORTDIR/metadata/timestamp* and add an 'until' param to the URL to filter commits beyond where a user has rsync'd up to... Cheers, malc.
