[Lxc-users] Using common rootfs for multiple containers

[Joshua Randall]

We have a particular use case, but we are achieving this using CernVM-FS (http://cernvm.cern.ch/portal/filesystem) to supply read-only root filesystems to many machines (with local caching), and then aufs or overlayfs (depending on the kernel version) to provide write support as others have suggested.
