** Description changed:
+ [impact]
+
+ root fs is not cleanly unmounted on shutdown
+
+ [test case]
+
+ create a file in /etc/binfmt.d/TestFormat.conf with the following
+ content:
+
+ :TestFormat:M::XX::/bin/true:F
+
+ reboot the system, and then shutdown or reboot again, and watch the
+ serial console for the error message
+
+ [regression potential]
+
+ any regression would likely cause problems on shutdown and/or reboot, or
+ may cause problems with unmounted root fs on shutdown/reboot
+
+ [scope]
+
+ this is needed only for f
+
+ this is fixed upstream with PR 15566 which is included in v246, so this
+ is fixed already in g and later
+
+ this isn't reproducable on b
