Are you finding something specific about that disconcerting? Personally I think having the ability to rebase branches should lead to a cleaner Git history (which is more readable and therefore hopefully more secure). I dislike the idea of treating branches as stateful as that makes them much harder to manage and use, it should be possible to push some commits to a non-master branch, then decide that's a bad idea and remove them without fuss. Maybe it also comes down to whether committers are interchangeable or not. If one persons signature on a commit is viewed differently to someone elses, then maybe there's an issue. I don't believe the Signed-off lines are being added to when rebasing, that still reflects the person or people who took the patch and initially pushed it to a branch. There should still be the extra information about the committer and signature key though. --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQKlBAEBCgCPFiEEPonu50WOcg2XVOCyXiijOwuE9XcFAmbbXMlfFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldDNF ODlFRUU3NDU4RTcyMEQ5NzU0RTBCMjVFMjhBMzNCMEI4NEY1NzcRHG1haWxAY2Jh aW5lcy5uZXQACgkQXiijOwuE9XdY2RAAiSSc7qa69lKPT0jCGhsBgIF+vpzKnwp7 QHUGFP99JExtMzuc0zKJGHz06aV4BPmLtsgHmoQ8Q7zq3a0IeC9b5FOc/YYL5dZK yIfhU+cmwLZ9MEMZniw3uG6d+X+VdQ8bMtanAJ5h9xiPgELmFeRNpwK2BVy4fbmx C+4eDP3bGIE/WHw9tBEKJcHz6ds1256DEQNCkH/mBEA36Dq9aJfX9sSJRXnFXche gMt7AZMzSz+9y6cfHTvU5C9yXDYoLJlEe6IfqpxYA8Ae0bXfexq1/Q1jKBvVFIkI NZY6oAfByFocXy7LoxDLb9LHG9pij64SDBmY9Pl/x5u+jCd/8UF5qT2F3QrXPx+1 Fqp5q+2BNorb+9fL3b2aneOdliuFdjIaeCmS6nVN0R2UAx881heecJZChHS78Un2 bR9Rk2QYOf/T4g88h8ZaJhErbwQUPX4ZQeeFqGiMvf4hDkqURYmX6qimAaTBDIQZ sZvjDhx7L8bpcNxn6O1RwKjMsEnWIQ88UwVkhXN1DytzC+4qwHLuENSvJDBPCNmP x+NLzzwYuXQThsZYbS1oqdLwHJDRUu6vvqKTezjlvAiUBPsHn+o7F7bUtN5ec7Gq sOB6qxXrYtacxGrReIJT9tx3YYcz8DtQzDNrpXXvaONip/sC6XpvQ29qvY9uiYoQ 8AYmcWcu6BU= =HcqP -----END PGP SIGNATURE----- --=-=-=--
