Appendix D. SELinux General Types
This appendix includes several tables
describing SELinux general types: types that tend to be referenced by
multiple domains. The types shown in Tables
1 through
5 are those
present in the Fedora Core 2 implementation of SELinux. SELinux
developers may introduce new types or delete existing types in other
SELinux releases.
