As this lower bound is not hard coded but dynamically calculated by the installer according to the size of bits to be installed, it reflects actual needs as far as necessary minimum space is required - it is currently ~4GiB. However, the absolute minimum always includes minimum swap space, which is now 512 MiB. I think the algorithm might be modified, so that swap space is not created if space doesn't allow it, but to be honest I don't know if this is what we want to allow for normal user.
