You can also use the "logger" directive to avoid using the default
Logger (which goes to $stderr) instead:
http://unicorn.bogomips.org/Unicorn/Configurator.html#method-i-logger
You'll also need to reconfigure Rack::CommonLogger and/or whatever
logger your framework (e.g. Rails/Sinatra) uses.
In modern versions of Ruby, the Logger class also seems multi-process
aware when doing its internal logrotation.
There is also SyslogLogger RubyGem which provides a Logger interface but
goes directly to syslog.

I prefer to log to files and use logrotate using a config as in
http://unicorn.bogomips.org/examples/logrotate.conf as Ben pointed out.
But you can also point those to FIFO + chronolog as Hleb pointed out,
too. That might be a little slower because of the context switches
and synchronous wakeups.
