I'm a newbie setting up my first miner, an Avalon 841.  I'm using the OpenWrt firmware via a raspberry Pi and am trying to set up my pools

I have two pools set up.  The way OpenWrt is working, Pool 1 is always active.  Pool 2 is never active.  The web-based setup doesn't seem to have an option to activate pool 2.  I can change pool 1 to pool 2, but of course that loses all the earlier data from the CGminer Status page.  Maybe there's no other way of doing it?

I've looked at the direct commands for CGMiner, but I didn't seem to see one that would activate a pool... and I'm not even sure I can run direct commands via the shell while the unit is being controlled by the OpenWrt application.  I tried and it seemed to run another instance of CGMiner... or something... couldn't tell if it was working.  I can get around some in a Linux shell, but I'm no master by any stretch of the imagination.

On that note, as I was looking for automatic ways to go between pools, I found the "quota" settings at the official CGminer README at in http://ck.kolivas.org/apps/cgminer/README that showed promise. (90% pool.ckpool.org 10% solo.ckpool.org)  That said, the config file at etc/config/cgminer on my Pi doesn't look like the same type of config commands...  and they seem to be generated by the OpenWrt application.  

Can I still use typical CGMiner commands in the config file there?

Thanks so much.
