From c025384103a9852f852d075337d1e2066253889f Mon Sep 17 00:00:00 2001 From: Stef Walter Date: Fri, 14 Aug 2015 16:38:41 +0200 Subject: [PATCH 2/4] journalctl: make sure 'journalctl -f -t unmatched' blocks Previously the following command: $ journalctl -f -t unmatchedtag12345 ... would block when called with criteria that did not match any journal lines. Once log lines appeared that matched the criteria they were displayed. Commit 02ab86c732576a71179ce12e97d44c289833236d broke this behavior and the journal was not followed, but the command exits with '-- No entries --' displayed. This commit fixes the issue.
