The file() thing here comes from the system() source. system() is
expanded at run-time, depending on the OS/platform/whatever syslog-ng is
running on.

You can run "syslog-ng --preprocess-into=/dev/stdout -s" to see what it
does with the config file. You'll find the file("/dev/kmsg") thing

Can you tell me the kernel version you have? And does this happen in a
container, VM, or on bare metal?

As a quick workaround, you can remove the system() line from the config,
and replacing it with whatever it expands to (see the command above),
without the /dev/kmsg part.
