Currently if a service is started by a socket (e.g. sshd.socket), journald created a new "unit name" per connection (e.g. sshd@0.service, sshd@1.service...)

It is then impossible to use the --unit option to display all the logs of the sshd service.

journalctl --unit should allow the use of wildcards for displaying the log data for several units at once.

This would allow to do something like "journalctl --unit sshd*" to display all the logs about sshd
