All, We've been gathering and porting patches related to namespaces in a lxc patchset for a while now. Mostly working on the network namespace which will require some extra work to be usable. * It's available here : http://www.sr71.net/patches/2.6.20/2.6.20-rc4-mm1-lxc2/ * Caveats : namespace syscalls are still under construction. network namespace is broken : . the nsproxy backpointer in net_ns is flaky. . the push_net_ns() and pop_net_ns() can be called under irq and are using current. this seems inappropriate. . there is a race on ->nsproxy between push_net_ns() and exit_task_namespaces() . does not compile with CONFIG_NET_NS=n pid namespace is still under construction. ro bind mounts should be pushed soon thanks, C.
