# Arch builds curl with HTTP/3 through nghttp3 + ngtcp2. Ubuntu packages
# neither, so the build host cannot satisfy them, and building both from
# source to reach HTTP/3 is a detour: nothing in the bootstrap needs it.
# pacman talks to plain HTTPS mirrors, and so does ERPLibre.
#
# DEFERRED, not rejected -- see TODO.md. Re-enable by building ngtcp2 and
# nghttp3 as Arch packages first, then dropping this hook.
