# Base + install command follow SideFX's own docker/Ubuntu/Dockerfile
# (shipped inside the Houdini tarball). Ubuntu 22.04 matters here, not just
# as a default: gccXX.X-tagged tarballs need a libstdc++ new enough to match,
# and Ubuntu's base image keeps libstdc++6 updated while RHEL/Rocky pin their
# system toolchain for the OS lifetime.
