That's the hash of the manifest revision, which implies that the
manifests are not byte-identical. You can do the same comparison on the
raw manifests with:

 hg debugdata .hg/store/00manifest.i a1f994465eb6fc082d7db05a59a38269993d0c60
 hg debugdata .hg/store/00manifest.i 8566b05d1c1fe370ce38a7186a381e2f7412a180

in the appropriate places.
