Because "filed" relies on chroot(2) and setuid(2), log files cannot reliably
be re-opened.  If you need log rotation then a second process, which can close
and re-open log files, must be used.  Any process may be used for writing logs
but if the process does not support log rotation then it will not provide that
benefit.  For example, if you wish to write logs to syslogd(8) you can use
logger(1), such as:
	# ./filed --root /www --user nobody --log '|logger -t filed' --daemon

Troubleshooting
---------------
   1. It won't compile, something about stdatomic.h not found or _Atomic not
      a valid type.

      => This is a bug in your compiler:
            https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58016

         GCC 4.7.x and 4.8.x define the macro indicating that they have C11
         support and do not define the macro that C11 requires to indicate
         that C11 atomics are not available.  They should define that macro.

         You can disable the features in "filed" that require C11 atomics by
         defining FILED_DONT_TIMEOUT in the Makefile.
