Subject: [PATCH v2 3/9] gnu: bash: Define the SYS_BASHRC macro.
Date: Tue, 13 May 2025 11:31:42 +0900

This causes Bash to treat /etc/bashrc as a startup file, removing the need to
source /etc/bashrc from ~/.bashrc.

* gnu/packages/bash.scm (bash-fixed): New package, with added SYS_BASHRC
define.
(bash) [replacement]: Use it.
* gnu/system/shadow.scm (%default-bashrc): Do not source /etc/bashrc, now done
implicitly.
