[rsyslog] rsyslog 5.3.6 (v5-beta) released

[Rainer Gerhards]

David,

thanks for the feedback - and a quick note.

With the new engine, you can do ruleset inclusion (via omruleset[1]). That is
probably *the* method to handle files that are written to by multiple
actions. Of course, no need to change if all works in default config. But you
can gain some extra performance by using buffered mode (for busy files) and
to use that, you need to have only one action write to each file. This is
where ruleset inclusion enters the game.
