Thanks. That gives me hope if I install a distro as the first
stage. I tried some different search terms after posting (the last
time I looked re SRCD and sticks I think I just got ubuntu
answers). This time I got an "official" link mentioning changing
various things, so it looks as id 'dd' is just for 'hybrid' ISO
files. I left the dev machine building dosfstools (thanks for
adding that, I didn't think I'd ever need it) so I can try different
approaches in the next few days.

Maybe it isn't - but it has some useful tools and will give
confirmation that whichever 'magic' key I hold down on a cold boot
(maybe F2, but depends who wrote the UEFI) does let me boot from a
stick.

I'm currently on my (ancient) netbook, copy-and-paste-in-urxvt
disappeared ages ago so I can't check that for the moment - but I
agree that it sounds odd.

Agreed, but a diversion from what I want to do.

I suspect I won't like gdu. Even just installing 'file manager' (I
suppose that is nautilus) has meant that a large number of downloads
default to opening in that instead of saving. So please don't
prioritise that on my account.
But thanks for thr comments on 'dd' - if I end up installing 'buntu
to bootstrap LFS, I'm hopeful that will work. And I wish I had
bought more of these sticks to play with, but using a 16GB stick
(smallest currently available) for something which is under 1GB
seems so wasteful.
