While poking around inside an extracted autotest_server_packages.tar I noticed this.

~/temp/server_packages$ ls ./autotest/quickmerge/chromeos-base/

I believe sbasi@ added something that dropped these files. But not sure why they are appearing inside the autotest server tarball. Seems like a probably harmless bug.
