Subject: [bug#75810] [PATCH v7 11/16] linux-container: ‘unprivileged-user-namespace-supported?’ returns #f on non-Linux.
Date: Thu, 20 Mar 2025 21:54:44 +0100

Previously this procedure would return #t on non-Linux systems.

* gnu/build/linux-container.scm (unprivileged-user-namespace-supported?):
When USERNS-FILE doesn’t exist, return (user-namespace-supported?).
