During the testing at least one of the tests does `setfacl -m group:0:1
tmpfile0`.  Obviously this gets a 'permission denied' error as group 0
doesn't exist.  What do you suggest for reasonable replacement for 0?
I'm thinking 11(Authenticated Users) as the purpose of the test is to
determine if the use of `set_acl (file, -1, mode);` will reset to a file
without acl.
