While updating Ansible I ran into an issue with an extras module for ZFS and Solaris. A playbook that used to work to set a mount point no longer worked. I was seeing errors that ended in

if int(version) >= 34:\r\nValueError: invalid literal for int() with base 10: '-'\r\n", "msg": "MODULE FAILURE"

An issue was filed in June and fixed last month. This change isn't in the latest Ansible 2.1.1.0 which I was using. For the time being I've added the extras repository devel branch as a submodule and used ANSIBLE_LIBRARY=... to get a fixed version.
