*The Lenovo C30 can boot the live system via eSATA*
I had problems to zsync the current daily Lubuntu Questing iso file, but
I could zsync the corresponding Ubuntu Desktop Questing iso file. And I
found a workaround.
I saw in the busybox (available after the complaints about /dev/sr0)
that the USB drive was not seen in the /dev directory, so I thought,
that maybe an SSD connected via eSATA might be more successful. And yes,
it works. As a bonus, wayland in the live system makes the live system
manage the nvidia graphics.

So there is still a bug, the USB boot drive is not seen as a device by
the new Ubuntu version (not in the /dev directory).
However, I have a workaround, and I look forward to several years
running some Ubuntu flavour in my Lenovo C30 workstation.
