[issue15748] Various symlink test failures in test_shutil on FreeBSD

[Trent Nelson]

Trent Nelson added the comment:

Not really... the problem is that the chmod 0007 actually corrupts the ZFS metadata regarding the symlink by always setting the length to 24.

Andriy did some debugging here: http://lists.freebsd.org/pipermail/freebsd-fs/2012-August/015005.html

So, the link basically becomes invalid once the bug hits.

Here's another option I just thought of: change the tests to use something other than 0007, then add another test specifically for this issue.
