I think we are talking about different things :)

What I meant is that if you keep the exported specs under version
control, you will want the packages to be in the same order every time.
Other wise, you could very well have

A
B
C

then on next export

A
C
B

which is the same, but will warrant another commit in your repository
(for no good reason).
Ideally, we would like to avoid useless  commits.

As you mentioned in the other email, I think a more convenient solution
to this is to use the format that I suggested which will include the
provenance.

This will save the use from having to deal with too many CLI parameters.

Which I'm still against.  I find that including the specs within the
profile is a much better idea: less effort, plus it ties the spec to a
profile, thus giving a relationship guarantee to the user.

Cheers!
