The backtick thing is intended, I'm afraid: in syslog-ng 3.3, ` is used
by the configuration parser, therefore, you can't use it as you did
before.

I don't think such usage was anticipated, otherwise this change would've
been mentioned in the NEWS file.

The solution is to use $(...) instead - that's supported by all POSIX
compliant shells I know of, and even some others.

As for the zombie processes, that's an unrelated thing, and a bug
indeed, one which I'm working on.
