So I think the current prescripts behavior is incorrect. That is, when 'next' happens, ACTION should be set to the actual value rather than 'next', as is the case today.
Fixing this means anyone relying upon the current broken behavior of next would potentially be affected. My bet is no one is doing that and we would be ok should that be feasible. Anyone disagree with fixing ACTION to not say 'next' but instead say what next really means?

However, the documentation implies it should get called when the install finishes. Do I really need to monitor it through xcatmon if I want to hook a node having completed it's boot? (Oh, and by the way, when reinstalling a node, xcatmon never goes to the installing state. So I literally would have to hook both these places and create my own datastore both scripts can talk to if I want to be able to catch nodes being set to boot AND nodes being set to install.)

In the case where you expect "boot" section to be called, you suppose to issue the "nodeset <nodes> boot" command. Then, does the script ever get called in this case? If it does, what is the value for $ {ACTION} ?

The behavior is that rinstall/winstall are just simple shell scripts. Upon completion of install, the next entry in chain.currchain is used as the argument to 'nodeset' (effectively). For example: nodeset <noderange> runmcd=bmcsetup nodech <noderange> chain.currchain=osimage=blah,boot Would cause bmcsetup, then deployment of blah, then boot to storage.

In order to do so, I'm trying to hook the nodeset command. Per the nodeset command manpage: "nodeset is called by rinstall and winstall and is also called by the installation process remotely to set the boot state back to "boot"." This however, doesn't appear to be the case. I can successfully hook the node being set to install, but not it being returned to the boot case. Since there has been discussion here about features for 2.9 and documentation has come up, I thought I'd throw out that this is in fact the second instance of something like this I've run across in the process of setting up this software. Please, please, PLEASE consider a complete documentation revamp for 2.9. Otherwise no matter what features you have, people will be leaving for management systems where they can count on the documentation being correct.
