Comment 5 for bug 1247769

Hi Joseph,

Due to the headaches introduced by bug 882147 (which effectively guarantees that tests will fail erroneously), we are changing the Upstart tests to detect a /tmp overlayfs filesystem and display a warning. One approach is to make use of OVERLAYFS_SUPER_MAGIC to check /tmp. See below for the discussion:
