Yes. Which basically means, you *cannot* have both a) rebase only merges and b) every commit must be signed as policies. At very best, I think either a) a future git might support signed rebases ( ie: replacing existing signatures with new signatures in the name of the person performing the rebase ) or b) somebody could write a wrapper that provides signed-rebase support until git get around to implementing it natively. and even then, you're going to lose original signing info ( Though, thats no worse than the signer of the manifest file changing every sign ) -- Kent perl -e  "print substr( \"edrgmaM  SPA NOcomil.ic\\@tfrken\", \$_ * 3, 3 ) for ( 9,8,0,7,1,6,5,4,3,2 );"
