[Bug 913877] [NEW] lxc-create fails: cp: will not create hard link...

[Robie Basak]

Public bug reported:

Steps to reproduce:

1. Start with a machine running a fresh Precise cloud image
2. apt-get update && apt-get dist-upgrade
3. apt-get install lxc
4. cat > lxc.conf <<EOF
lxc.network.type=veth
lxc.network.link=test_network
lxc.network.flags=up
EOF
5. lxc-create -n test_container -t ubuntu -f lxc.conf -- -r oneiric

Command fails with:
Download complete
Copy /var/cache/lxc/oneiric/rootfs-amd64 to /var/lib/lxc/test_container/rootfs ... 
Copying rootfs to /var/lib/lxc/test_container/rootfs ...cp: will not create hard link `/var/lib/lxc/test_container/rootfs/run/shm' to directory `/var/lib/lxc/test_container/rootfs/dev/shm'
Failed to copy rootfs
failed to install ubuntu oneiric
failed to execute template 'ubuntu'

Oddly, note the inode numbers below:

dev and run appear to be independent directories:
