Can't start pyrex in LXC container about pyrex HOT 1 OPEN

Pyrex heavily relies on bind mounting filesystems into the container to make it efficient and "seamless". Because of this, it can be particularly tricky to run Pyrex inside another container. Success will depend of if you are running DinD or DooD. I've had some success doing it with DooD, which basically means you're still doing checkouts and stuff in the container host, then passing the correct paths to Pyrex (which, may not match the paths in LXC!), but I don't really recommend it. DinD is probably quite difficult or impossible to accomplish. It does beg the question: if you have a LXC container, why do you need Pyrex? It seems like you could modify your LXC image to include all the things you need instead.
