os-z-base -- an immutable base image for an os-z system
`os-z-base` is a read-only system image that contains the kernel, the system libraries, and the system service binaries. This image can be built with a variety of options to restrict or expand its capabilities, based on the context in which it is expected to be used. All capabilities must be explicitly enabled.
This is part of the OS/z User Manual. See `copying.7` for copying conditions.
