Description Orion Poplawski 2013-07-18 17:22:28 UTC

Since I think journalctl generally only handles messages for the local machine, is it even necessary to output the hostname, esp. the fully qualified hostname?

At the very least, options to be able to shorten or eliminate the output of hostname would be nice.

We show the kernel hostname, not the fqdn. If you initialize the kernel hostname to the fqdn it's kinda your own fault...

journalctl handles messages from as many hosts as you like. For example, if you share the journal dir from multiple hosts, you can use "journalctl -m" to merge the output of all of them. This is also used by "systemd-nspawn -j" to make the logs available easily. 

Also we try to stay compatible with classic /var/log/messages in our output, so that people can parse the lines with the classic tools.

All together I am really not convinced that it would be a good idea to not show the name.

Well, FWIW - IPA/kerberos appears to demand that the hostname be set to the fqdn:

Joining realm failed: The hostname must be fully-qualified: barry

So I still think this would be a useful option.
