+Subject: [PATCH] casd: fix default cleanup-threshold test on non-x86
+
+CmdLineSpecTest.NoActionCacheProxy fails on aarch64, ppc64le
+and s390x with the following:
+
+  casd/test/buildboxcasd_cmdlinespec.t.cpp:310: Failure
+  Expected equality of these values:
+    0.8775
+    daemon.d_cleanupThresholdRatio
+      Which is: 0.87750000000000006
+  [  FAILED  ] CmdLineSpecTest.NoActionCacheProxy
+
+Assert the computed default instead of the rounded literal.
+
+The helper is shared with configure() so the expected value
+is the same expression, not a second copy of 0.65 in the test file.
