This '--manifest' option accept a file, which should return a manifest
object, and the script you run generate it from your profile.  So you
can write the script output "(specifications->manifest .....)" into a
file, eg: "~/.config/guix/manifest.scm", then use "guix package -m
~/.config/guix-manifest.scm" to apply it.

No, the "packages" field of "operation-system" accept a list of package
objects, it can't deal with "manifest".  In fact, "manifest" is used to
manage user's own profile, in a declarative way, just like "packages".
