Subject: bug#40998: [PATCH 2/4] system: Streamline operating-system-boot-parameters-file a bit.
Date: Mon, 28 Feb 2022 17:50:44 -0500

* gnu/system.scm (operating-system-boot-parameters-file)
[SYSTEM-KERNEL-ARGUMENTS?]: Remove unused argument (it had no callers) and
adjust doc, moving the self-referential tip to...
* gnu/system.scm (operating-system-boot-parameters): ... here, reworded for
clarity.
