This appears to be a problem with the
install-amd64-minimal-20160908.iso image's kernel. Looks like there's a
bug in it that prevents it from recognizing or using USB drives. dmesg
from the shell shows it can't even see USB drives when they're plugged
in. Yes, I tried multiple drives, and said drives work fine with a
vanilla kernel. No label problems, just "we didn't bother to test
whether the USB storage system worked".
(I have run into enough weird bugs with Gentoo's supplied kernels that
now I grab a vanilla tarball and build it as soon as I can. YMMV.)

This seems odd, because when you dd something to a raw device, you
shouldn't even have to write a label--the label is already in the ISO
(or whatever).

We will always have the old stuff with us, because the new fancy stuff
so often overpromises and underdelivers in spectacular ways.
