Yes. However, I just noticed a more serious problem.
The "independent verification" that you and I performed at commit
4ae7dc7b9af64794081b1913740b97acd89c91bc was bogus, because at that
commit, %bootstrap-inputs had already been changed to use an earlier
draft of the reduced binary seed, based on unverified bootstrap tarballs
downloaded from lilypond.org.
In order to perform a truly independent verification, we need to build
the new bootstrap binaries without using the new bootstrap binaries.
Otherwise our verification is circular.
It seems to me that the best way to accomplish this is to backport the
new '%bootstrap-tarballs' from 'wip-cu-binaries' to the 'master' branch.
What do you think?
Thanks,
Mark
