I'm trying to follow the doc to setup LXC (http://wiki.gentoo.org/wiki/LXC) and am unable to find this option. I manually insert it ane make menuconfig again and it gets removed. I see the other options the doc references: [*] UTS namespace [*] IPC namespace [*] User namespace (EXPERIMENTAL) [*] PID Namespaces [*] Network namespace
But not 'User namespace' - is there something that has/needs to be enabled/disabled for this to work? I grepped through the 3.8.0 and 3.5.7 source and see about the same number of references to this config option, and the only thing I found in googling was these namespace options are expanding, so I'm guessing it wasn't removed?
