Is it just me, or is rebasing branches disconcerting, as it likely means
the person signing the commit is not necessarily the original person
pushing the commit? This is worst for the now deprecated core-updates
branch with many rebased commits... are people still updating the
signed-off-by tags or whatnot?

Though, of course, there are problems with merges as well I recall being
discussed on the list in the past...

live well,
