Hi, I haven't really tried, I only wanted to look at fig 1.0 currently in f21 updates-testing. So I --shell'ed inside my fedora-21-x86_64 mock chroot after installing fig, and tried to start a docker daemon in the background but it failed. # docker -d -H unix:///var/run/docker.sock & 2014/11/05 23:08:33 docker daemon: 1.3.0 c78088f/1.3.0; execdriver: native; graphdriver: [45f3a6fd] +job serveapi(unix:///var/run/docker.sock) [error] attach_loopback.go:42 There are no more loopback devices available. 2014/11/05 23:08:33 loopback mounting failed If I need to use a VM, I will (any news for vagrant?) but I was wondering whether this was actually possible. I haven't looked in detail at how mock creates the chroots, and don't have time to dig at all these days. I was just wondering whether it was actually possible to run docker in a chroot, especially one built with mock!
