Force LogStash to read End of File?

Hi was wondering if anyone had a cunning way to force LogStash to always read the end of a file , no need for a sincedb_path file etc whether the logs are new or not after say a Logstash restart?

The only current out-of-the-box method seems to be is set the flag start_position => "end" (default value) and remember to delete that sincedb_path file before starting up Logstash which requires manual intervention or a bespoke startup script.

Was going to put in a feature request for a 'always' or 'force' read end of file flag but wanted to ask if people had any other ideas first.

Regards

Setting sincedb_path to nul (Windows) or /dev/null (anything but Windows) will effectively disable sincedb.
