I guess if you were running multiple clusters and having them all log
to the same syslog daemon, there might be multiple clusters' output
in the same log ... but we already have ways to disambiguate that case,
ie, syslog_ident.  Likewise for Windows' event log.  I don't think we
should consider it supported for multiple clusters to be logging into
the same plain files.  So yeah, the use case for this seems unclear.
