You cannot mknod inside unprivileged containers, the kernel just won't let you. Either you need to work around the problem by moving around a compressed tarball without the /dev entries and bind-mount the ones from the container /dev onto them instead, or go the easy way about it and just make the container privileged with 'lxc config set NAME security.privileged true'. You'll then most likely hit another restriction which is about mounting potentially dangerous filesystems in unusual locations which our apparmor profile blocks. To turn that retriction off, running 'lxc config set NAME raw.apparmor "mount,"' should do the trick. Once you've done those two config updates, restart the container and things will hopefully work fine. -- Stéphane Graber Ubuntu developer http://www.ubuntu.com
