Every =E2=80=98guix=E2=80=99 command has at least a corresponding procedure=
.  So =E2=80=98guix
package=E2=80=99 matches precisely the =E2=80=98guix-package=E2=80=99 proce=
dure of (guix scripts
package).

When this is too CLI-ish, you can use more Schemey APIs.  For instance,
=E2=80=98guix package=E2=80=99 relies on things in (guix scripts) and (guix=
 profiles).

As for your specific use case, I would argue that you could implement it
as a service.  The service would take a list of user/manifest pairs as
its configuration and simply have an activation snippet that installs
the user profiles.  That would be a useful feature to have.

HTH!
