[syslog-ng] running syslog-ng and syslogd concurrently?

[Matt Camuto]

Thank you - This is what I was looking for. I will work with my architecture team to try to get this to work. I think it should be fine.

Well, I guess you are using the new syslog-ng 3.0 installer, which does
way more than the previous ones to make it easier to deploy syslog-ng.
But you are right, its model is to disable the stock syslogd and replace
it with syslog-ng.

However it is possible to skip the installation script, in which case
only the binaries are loaded to the machine and no installation is
performed.

If you run the installation program with the --noexec argument, the
embedded installation script will not be run, but still the contents of
the archive are extracted. Basically the .run file is a self-extracting
tar file.

Once you have the binaries, you are free to change your system in a way
that lets you run both syslogd and syslog-ng at the same time.

Since their files on the disk do not conflict, and it is possible to
create configurations for both that do not conflict, it is certainly
possible to run the two in parallel.
