chain.currstate is the state which will be used for current operation. For each 'next' switch (nextdestiny), the state will be shifted out from chain.currchain to the chain.currstate. If the chain.currchain is black, copy the state from chain.chain. At last if found the chain.currchain is black, make the chain.currchain has same state with chain.currstate.

When doing a nodeset node rumcmd=something, I would expect it to change chain.chain to runcmd=something, keep chain.currstate and chain.currchain to whatever it's currently doing, and when on reboot it would see that chain.chain is now runcmd=something and execute it, and update chain.currchain and chain.currstate when it begins execution. Instead, it sets chain.currstate to whatever I put in nodeset, and chain.chain and currchain are never touched. I've read the man pages and whatever I could find on sourceforge about the chain table, but confusion still abounds. Is there any other documentation out there regarding the chain table, or could somebody perhaps clarify a bit more on what each piece of chain table represents and how they fit in to the rest of the xcat system?
