The minimum was changed by https://help.ubuntu.com/community/Installation/SystemRequirements?action=diff&rev2=108&rev1=107
about 1 year ago. My understanding is that the minimum is 2GiB while the
recommendation is 4GiB? (I'm unsure how to read the 4GiB mentioned in
that page ;)
Is 16.04 impacted by these changes in memory requirements though?
