I am confused about this issue and the google search has limited information.
Some people say they need systemd v229 or higher to support it.
The update log from Red Hat indicates that support has been available since RHEL 7.3.
But this conflicts with my query results. Which statement is correct? Is there any way to confirm the actual support of the Ambient capabilities?
