The non-hygienic binding of the source location accessor was set to
'-location'; in modules where multiple configurations were defined, it would
cause compilation warnings such as:
gnu/services/mail.scm:175:0: warning: shadows previous definition of
`%-location-procedure' at gnu/services/mail.scm:165:0
* gnu/services/configuration.scm (define-configuration-helper) <id>: Add a
missing #'stem argument to use the configuration name as a prefix to the
location accessor identifier.
In some cases, rather than globally disabling serialization, it may be more
appropriate to disable or otherwise alter the serialization procedure of a
specific field. In large module, multiple configurations may also exist that
would need to alter the default serialization procedure, which is named after
the field type. Being able to specify a per-field serialization procedure
provides more flexibility.
* gnu/services/configuration.scm (define-configuration): Add an optional
pattern variable to allow specifying a custom serialization procedure.
(define-configuration-helper) <field-serializer>: Use it to transform the
syntax.
(empty-serializer): New procedure.
(serialize-package): Alias to ‘empty-serializer’.

Serialization is not always useful, for example when deriving command line
arguments from a configuration. This change provides a way to turn it off,
which removes the need to define a bunch of dummy serialization procedures.
Credit goes to Andrew Gierth (RhodiumToad) from #guile for providing the
solution. Thank you!
* gnu/services/configuration.scm (define-configuration-helper): New procedure.
(define-configuration) <no-serialization>: New syntactic keyword. Use it in a
new pattern. Refactor the macro so that it makes use of the above helper
procedure.
This resolves a compilation warning introduced with commit bb716e8d9d.
* gnu/services/configuration.scm (configuration->documentation): Use display
to print the string instead of format.
This has been the recommended default for arm and arm64 since since
v5.9 (upstream commit f259eab3ea0e7ed73db91f6358274dd3a9a27d79).

Wget is typically included with most GNU/Linux distributions. It adds about
~3 MiB to the system size.

This package is part of the Python standard library since CPython 3.3.

The original (undocumented) procedure to generate the doc has a difficult to
grasp interface; add a simpler one on top of it.
* gnu/services/configuration.scm (configuration->documentation): New procedure.
Not all fields in a configuration have a sensible default value. This changes
makes it possible to omit a default value for a configuration field, requiring
the user to provide a value.
* gnu/services/configuration.scm (configuration-missing-field): New procedure.
(define-configuration): Make default value optional.
