That is our preferred way of handling libc++/libc++abi bots, because that means anyone can reproduce the failures locally. If the bots don't require anything specific beyond the CMake configuration they're testing, you could even use our existing Docker images based on Debian.</div><div><br class=""></div><div>Louis</div><div><br class=""></div></body></html>
