Interesting... Wouldn't that construct result in one massive syslog
entry containing many lines of the nginx log (possibly overflowing a
syslog max limit and truncating)? The default interval for tail -f
seems to be 1s. That could be solved by an intermediate process I

Unfortunately, I see no mention of TLS support in the man pages for
logger, but I think you are on to something... good suggestion. The
efficency of tail -f is the deciding factor I think.

Coordinating with log rotations will also be somewhat tricky, but
probably do-able by watching the descriptor instead of the name and
re-starting the process at log rotation.

I still think native syslog in nginx is more desirable, of course.
Complexity is the enemy of both stability and security.
