The named_t domain can only be transitioned towards through the initrc_t domain (i.e. through init scripts). The ndc_t domain (for the named domain controller) can be transitioned towards through the initrc_t and sysadm_t (general system administration) domains.

Using the bind SELinux module

SELinux boolean: named_write_master_zones

The named policy offers one boolean called named_write_master_zones which, when enabled, allows the named daemon to write to its master zone files (i.e. named_zone_t). This is used in master/slave setups.
