+Subject: [PATCH] t/spawn: Find invalid PID to try to join its process group
+
+In the container used to build packages of the GNU Guix distribution, PID 1
+runs as the same user as the test so this spawn that should fail actually
+succeeds.
+
+Fix the problem by going through different PIDs and picking one that
+either doesn't exist or we aren't allowed to signal.
+---
+
+This patch is taken from the public-inbox repository and will appear in the
+release after v1.8.
