Bundles lose symlinks

[nOw2]

I have in-house source packages into which I want to add symlinks for directories. These work fine except when I create a bundle (we use bundles to release code to production).

The bundles are zip files which is where I believe the symlinks are being lost. 'unzip -v' on the bundle shows the broken symlinks, turned into empty directories.

Found this comment - my vote is definitely to move to tar since on testing it preserves symlink information.

pip/req.py:
    def create_bundle(self, bundle_filename):
        ## FIXME: can't decide which is better; zip is easier to read
        ## random files from, but tar.bz2 is smaller and not as lame a
        ## format.

mksquashfs is the coolest way to preserve symlinks
