Thanks for the note. -B is not the default for etcupdate. Because of that, it would probably help if the various places that document using etcupdate for the 99% type of context had an explicit "normally use -B despite it not being a default" and "omit -B only when the source tree version has not been built yet". Such might be easier to follow than just the existing wording. Although, the lack of -B for diff, resolve, revert, and status is messy. If those silently ignored when -B , the instructions for use of -B could be simpler. =3D=3D=3D Mark Millard marklmi at yahoo.com
