iocage jails do seem to be better under 11.2.
The UPS bug referred to shuts down the system when the UPS battery gets low - regardless of how you configure the system to behave. I don't think this would be a showstopper for most home systems, but I will be watching for the fix. I don't like waiting for the UPS battery to report low and then hope there is enough power for the system to shut down gracefully.
