12 Yes. Which basically means, you *cannot* have both
13
14 a) rebase only merges
15 and
16 b) every commit must be signed
17
18 as policies.
19
20 At very best, I think either
21 a) a future git might support signed rebases ( ie: replacing existing
22 signatures with new signatures in the name of the person performing
23 the rebase )
24 or
25 b) somebody could write a wrapper that provides signed-rebase support
26 until git get around to implementing it natively.
27
28 and even then, you're going to lose original signing info ( Though,
29 thats no worse than the signer of the manifest file changing every
30 sign )
