Alternatively, introduce a new environment variable. Call it, say,
EX_ACTION (executing action). It would contain the name of the
action being executed. ACTION can therefore stay as 'next', letting
you be backward compatible, while still getting the new feature.

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?

And yes, if I explicitly call "nodeset <node> boot" the
boot section gets called (with the value "boot" for ACTION).
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} ?

What was attempted that failed?
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.

Hi all,
I have a piece of software I'm deploying into a cluster that
requires
some setup be done on the head node. 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.
