Doesn't work in Fedora 10. One mistyped selector, and an entire
rule is ignore
silently. See comment 14.
By the time rsyslog parses the config file, it is already forked and without
access to stderr.
(Rainer, there's actually a bug in that rsyslog always tries to write to
stderr. :) When forked, it accidentally writes to the file opened with fd 2.
Hope the patch got to you.)
So IMO a reasonable solution is to change the code to return some non-zero
value when -N encounters an error, run rsyslog -N first, discard the output as
not to spam the screen and if retval != 0, print a warning about config file
syntax a then start the daemon.
What do you say?
