4 GiB RAM is not enough

[j77h]

At https://ghostbsd-documentation-portal.readthedocs.io/en/latest/user/installation-guide/getting-started.html#system-requirements
under "System requirements" it says
"4 GiB RAM (system memory for physical and virtualized installs)",
but this is not enough.

I tried to install GhostBSD-25.02-R14.3p2-XFCE.iso
on a laptop with 4 GiB of RAM, and the installer quit
before it finished loading itself into RAM.

The bytes of RAM it stated as available and required
were exactly the same.

I guess you need to allow for the fact that
some of the RAM is already in use, for the video buffer
and the installer process that is running at the time.
