I emailed a log with my attempt at analyzing it to Colin Watson the
other day and am still waiting to hear back from him.  I think you can
close this bug now as I'm fairly certain it is an Ubiquity issue.  I
looked at some logs from older releases and indeed they all seem to run
all of the init.d scripts first, and only later process the visual.d and
other scripts, so somehow ubiquity must be running things wrongly and
getting the visual.d scripts to run before the init.d ones and that is
the cause of the problem.

I do still wonder though, why the script doesn't trip up when installing
from a USB stick.  Is there some logic somewhere I don't see that causes
all of partman to ignore/forget about the disk you are installing from,
so that the efi script doesn't see that and count it as a non ESP?
