Comment 0 for bug 787749

The following configuration required for LXC is currently missing for linux-ti-omap4:
 - CONFIG_USER_NS
 - DEVPTS_MULTIPLE_INSTANCES
 - CONFIG_SECURITY_FILE_CAPABILITIES

These are at the least the obvious ones as reported by "lxc-checkconfig".

Below is the output on ARM and on x86:
