That just means Ubuntu is using the wrong shell (i.e. not bash), or the
wrong set of shell options. See the section in the bash manpage on
brace expansion, and note that it can be disabled if "set +B" is run or
bash is started with the +B option. And of course, the original sh
didn't do brace expansion, so nothing requires other sh-compatible
shells to support it, either.
But the book already sets up the lfs user to use the bash shell: see
section 4.3. If you've duplicated this issue, I would double-check that
you're really using bash, and then "set -B", to see if that helps.
