You=E2=80=99re not missing anything: it=E2=80=99s a longstanding source of = confusion that these =E2=80=98manifest=E2=80=99 files are not like the =E2=80=98manif= est.scm=E2=80=99 files. These =E2=80=98manifest=E2=80=99 files are meant for internal consumption. I think Pierre Neidhardt started looking at ways to address it from different angles, but that hasn=E2=80=99t materialized yet. One thing we discussed was to add an =E2=80=98--export-manifest=E2=80=99 (or similar) op= tion that would export a =E2=80=98manifest.scm=E2=80=99 file for a profile, where the =E2=80=98manifest.scm=E2=80=99 file could be an approximation of what the p= rofile contains, in some cases. > If not, does it seem reasonable to make the `manifest' files automatically > deserialize into the objects they describe?
