Indeed, I had forgotten that we had actually reached consensus and then stalled at the point of getting the list of allowed-to-deviate builtins settled. Colin had proposed the winning solution, IIRC. The only builtin which we identified needed to be on that list was test itself, and the problem here was that the deviations in posh's implementation of test would pose serious problems. That could be solved by saying something like "test may be builtin in inconsistent ways, provided that X, Y, and Z features still are supported." That could be written (by careful choice of X, Y, and Z) to enable bash and dash to pass muster and still avoid the problems that supposedly are raised with posh. The other solution--which may be an acceptible short-term one, is to specify explicitly that shell scripts must work with Debian bash and Debian dash. I have no objection to that, and continue to think it is the simplest approach. As always, I am happy with just about any of these solutions, but the charge-blindly-ahead method is not good.
