another update. Also intended to be merged to quarterly branch.
poudriere tested on 10.4, 11.1, HEAD amd64 and 10.4 i386
@swills I contacted the author and he promised me to eventually stop this updating. Clearly this hasn't happened yet. So I would suggest once the next version is released, we stay on the "stable" one (i.e., this one) and only update to 5.8 once 5.9 is out.
@mat thanks for the comment! Will use 10.3 and 11.0 jails again.
