Ah, you are right!  https://hydra.gnu.org/build/3194622/log/raw (the usb-image
for i686) also fails - but nobody noticed because we only distribute the iso
image (which determines its size dynamically).

I didn't make the connection that this is a fixed-size guest filesystem before.

Probably!

According to the progress bar it's missing an additional 40% ?  That's... large.

I've increased the size for the time being, but according to the logs
it was at 800 MiB in 2015.
