Issue/Introduction

When booting up your linux server it stops halfway through and displays the message; Your default context is user_U:system r:unconfined_t

Resolution

When booting up your linux server it stops halfway through and displays the message:

Your default context is user_U:system r:unconfined_t.

Do you want a different one?

The system then waits for you to make a decision before continuing the boot process.

This message is a result of features that come with NSA Security Enhanced Linux.

SELinux uses security contexts to enforce policies. These contexts usually comprise of four fields: User field:Role field:Type Field:Security Level Field.

User-U is reserved for unprivileged users, and system_r is for role_based application roles. Unconfined_t simply means these processes are mostly not being confined by the SELinux policy but are still governed by standard Linux/UNIX security.

If you would like to bypass this prompt on startup, make the following change in /etc/selinux/config:

SELINUX=disabled
