another log question about solr 5

[elisabeth benoit]

Hello again,

We're planning on using solr 5.5.2 on production, using installation
script install_solr_service.sh.

I was wondering was is the right way to prevent solr 5 from creating a new
log file at every startup  (and renaming the actual file mv
"$SOLR_LOGS_DIR/solr_gc.log" "$SOLR_LOGS_DIR/solr_gc_log_$(date
+"%Y%m%d_%H%M")"

Thanks,
Elisabeth
