I don't find it easy to understand or remember that d1.update(d2) modifies d1 in place, while d1.merge(d2) first copies d1.

Maybe the name can indicate the copying stronger? Like we did with sorting: l.sort() sorts in-place, while sorted(l) returns a sorted copy.

Then shouldn't it be a function (not a method)? dictutils.merge()?
