The Linux kernel configuration item CONFIG_USER_NS has multiple definitions:

User namespace found in init/Kconfig

The configuration item CONFIG_USER_NS:

• prompt: User namespace

This allows containers, i.e. vservers, to use user namespaces to provide different user info for different servers.

When user namespaces are enabled in the kernel it is recommended that the MEMCG option also be enabled and that user-space use the memory control groups to limit the amount of memory a memory unprivileged users can use.

If unsure, say N.
