Overview

This class is responsible for finding out which sockets trigger a given service.

When systemd is working properly, the relationship between services and sockets is cached in order to reduce the amount of calls to systemctl show. However, during the installation, where systemd is not fully operational, this class just tries to find a socket named after the service.

Examples:

Finding a socket

finder = Yast2::SystemdSocketFinder.new
finder.for_service("cups").class # => Yast2::Systemd::Socket
