Provenance

This lets you record provenance meta-data in generated homes. It adds a .provenance file, as well .channels.scm and .home.scm files when applicable.

These files allow you to recreate your home at a later point in time:

guix time-machine --channels=.channels.scm -- home build .home.scm

Main Configuration

Provenance meta-data is automatically generated by using the provenance-home-type service type.

Scheme Procedure: provenance-home-type

The type of service that generates provenance files for your generated home. Its value is a location object.

Scheme Procedure: (home-with-provenance h [configuration-file])

Return a variant of h that stores its own provenance information, including configuration-file, if available. When configuration-file is omitted, the location where h is defined is used.

Example Configuration

(home-with-provenance
  (home
    (data-directory "/data/alice")
    (configurations
      (list
        (user-home something-home-type ...)
        ...))))
