1833 # suite as root, where a test may expect "chmod -r file && cat file"
1834 # to fail because file is supposed to be unreadable after a successful
1835 # chmod.  In an environment (i.e. combination of what filesystem is
1836 # being used and who is running the tests) that lacks SANITY, you may
1837 # be able to delete or create a file when the containing directory
