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