In terms of SMF services this corresponds to the stability tag. If present, this tag can appear at just a few different places, but a common one is to the bottom of a service description (to indicate the whole service stability level), but just above a template tag if this last one is present.
It can assume the following values:
- Standard
- Stable
- Evolving
- Unstable
- External
- Obsolete
Example:
...
<service type="service" version="..."
name="..." >
...
<stability value="..." />
</service >
...
NOTE
The stability level may have an impact on property groups across a release boundary of a service, in that Stable and Evolving ones are always preserved (not deleted) while Unstable ones may be deleted. See smf_bootstrap(5) for more detail.
