[Curtis Hovey]

This is the error
jenkins at wily-slave:~$ sudo lxc-start -n curtis -F
ln: failed to create symbolic link ‘/usr/lib/x86_64-linux-gnu/lxc/sys/fs/cgroup/cpu/cpu,cpuacct’: Read-only file system
lxc-start: conf.c: run_buffer: 347 Script exited with status 1

lxc-start: lxc_start.c: main: 348 Additional information can be obtained by setting the --logfile and --logpriority options.

Attached is the log of what happened.

The wily-slave host uses the lxd ppa. it has a lower priority.
These packages were installed and get updates outside of regular wily-updates:
    sudo apt-get install --no-install-recommends lxc=2.0* lxc-templates=2.0* lxc1=2.0* python3-lxc=2.0* liblxc1=2.0*
