You can start taking screenshots long before /target exists.
As indicated above, screenshots are placed in /var/log/…
which is a filesystem created in memory for the duration of the
actual installation process.

If you don't want to go as far as "Save debug logs" in the main menu,
then you have to copy them somewhere yourself. Once /target _does_
exist, you could copy them there, but that means getting as far as
"Install the base system", which populates /target with something
recognisable as a system disk (meaning that, say, /target/root/ would
be available).

So, the quick way is:

. Alt-F4 to view the syslog
. Insert a fresh stick, and watch screen
. Alt-F2(or 3) for a shell
. Mount stick (device name just seen on log) onto /mnt
. cp /var/log/… stuff to /mnt/… (may as well grab the lot)
. Unmount stick
. Remove stick after activity ceases
. Alt-F1 to carry on installing

Cheers,
David.
