Subject: [PATCH] journal-remote: show error message if output file name does
c62b8e
 not end with .journal
c62b8e
c62b8e
`journalctl -o export | systemd-journal-remote -o /tmp/dir -`
c62b8e
gives the following error messages.
c62b8e
```
c62b8e
Failed to open output journal /tmp/dir: Invalid argument
c62b8e
Failed to get writer for source stdin: Invalid argument
c62b8e
Failed to create source for fd:0 (stdin): Invalid argument
c62b8e
```
c62b8e
And these are hard to understand what is the problem.
c62b8e
This commit makes journal-remote check whether the output file name
c62b8e
ends with .journal suffix or not, and if not, output error message.
