See the run_init utility program and its domain. It transitions to the system_u:system_r:initrc_t domain and then runs the user-specified init script, which ensures that any daemons are started with the appropriate user identity, role, and domain (because domain transitions are already defined from initrc_t for the daemon processes). The run_init program, like newrole, reauthenticates the user to ensure that the user wants to perform the transition (to help protect against invocation by malicious code).

We aren't actively developing the MLS code or policy at present. To date, we have focused on the RBAC and TE policy components, since these are viewed as being of greater interest to the Linux community. See the README.MLS file for a description of what needs to be done to make the MLS policy useable.
