From 4311b9a2f14ee411ec3dc8b050f8efa25afa0bc5 Mon Sep 17 00:00:00 2001 From: David Oberhollenzer Date: Wed, 15 Aug 2018 23:50:41 +0200 Subject: usyslogd: create abstraction for log stream management This commit seperates the formating and printing of log messages to files more cleanly from the message pump that retrieves the log messages. At a later point, other backends could be added more easiyl (e.g. forward the log message to some server).
