Comment 3 for bug 1852119

Thanks for the policy clarification. But as I understand it "4 GiB of memory is recommended for normal performance in basic workloads" referred to 4Gb of memory in total, not 4gb of free memory.

I'll ask again once there is a device with more than 4Gb of RAM, but FYI, since the raspberry pi may often be used for single tasks, a 4Gb ram machine might be just fine with that zfs overhead.

(I haven't seen any memory pressure issues with multiple headless 4Gb Pi4 machines running with ubuntu on zfs.)
