ERROR: test_copyxattr_symlinks (test.test_shutil.TestShutil)
----------------------------------------------------------------------
Traceback (most recent call last):
File "/opt/Python-3.6.0/Lib/test/test_shutil.py", line 505, in
test_copyxattr_symlinks
os.setxattr(src, 'trusted.foo', b'42')
PermissionError: [Errno 1] Operation not permitted: '/tmp/tmpvlu10qdm/foo'
----------------------------------------------------------------------
The problem is that "trusted" attributes (in this case trusted.foo) are visible
and accessible only to processes that have the CAP_SYS_ADMIN capability. The
current "skipUnless" guard is wrong: being root (UID 0) doesn't necessarely
imply you have CAP_SYS_ADMIN. For instance this test (and thus "make test")
will always fail in a Docker container unless it's started with "--cap-add
SYS_ADMIN" (which, in general, is not the best thing to do).
