Use cron to rotate your own config in place and restart the miner.

One thing in the same category I am more intered in is switching pool based on luck.

Say I have worked at pool 1 for 1 hour until its luck has decreased to 100%. Now I feel that I will get less profit from the rest of my shares. If I work 1 more hour, I will get half the pay I would have received if I had dedicated my miner to another pool with 100% luck.

Actually, after 2 hours, switching will give me:
1 hour that gets dilluted to 50% value (2 hour block)
1 hour at 100% luck.

So by switching, I would get 1.50 times the value compared to mining the same block to finish.

I am seeing more and more very long blocks, and bad pool luck. So would like to try something like that.
