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).
* gnu/packages/aux-files/linux-libre/5.10-arm.conf,
gnu/packages/aux-files/linux-libre/5.10-arm.conf,
gnu/packages/aux-files/linux-libre/5.11-arm.conf,
gnu/packages/aux-files/linux-libre/5.11-arm.conf: Enable
CONFIG_CPU_FREQ_DEFAULT_GOV_SCHEDUTIL, disable
CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE.
This package is part of the Python standard library since CPython 3.3.
* gnu/packages/python-xyz.scm (python-ipaddress): Merge with ...
(python2-ipaddress): ... this.
[name, arguments]: Adjust accordingly.
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.
