Thanks!
It is working fine now that I figured out what the issue is. We will gain a
lot better performance with site.precreatemypostscripts enabled, so we wish
to keep it on. This is a cluster with ~6000 nodes.

The question turns to whether to use the site.precreatemypostscripts.
This site attribute is used to improve the performance of postscript
mechanism in a big cluster.
If site.precreatpostescripts is enabled, the mypostscript for the
node will be generated by nodeset command on xCAT MN. When booting of
node, the created mypostscript will be copied to compute node
directly for using. The advantage is it can save the computing
resource of MN during the node booting process, the shortage is you
must run nodeset for each changing which related to postscripts.
If site.precreatescripts is disabled, nodeset command won't do
anything for mypostscirpt. When booting of node, it will try to
require the xCAT MN to generate the mypostscript at that time.
So for your issue, you can try to disable the
site.precreatemypostscripts and to see whether it works well.
Thanks

I figured out what's going on - we are using the
site.precreatemypostscripts=1 option. Even though the man page on the
site table states that the mypostscript file for the node should be
updated when an updatenode is ran as all as a nodeset, this is not
happening. I have to do a nodeset on the node to have that file
updated.
There's also a gap here in that since the node utilizes it's
local /xcatpost/mypostscript for pulling in variables that the
otherpkgs script needs, specifically $OTHERPKGDIR and $OTHERPKGS1,
you need to reboot your node or manually push the new copy of this
file to the nodes for your changes to OTHERPKGDIR in the osimage to
be seen by your node. In my opinion, enhancements to updatenode need
to be made so that:
A) updatenode rewrites the mypostscript file to capture any changes
you may have made to your osimage definitions
and
B) updatenode pushes this new mypostscript file to the node so that
updatenode will be aware of any osimage definition changes.

We are wanting to separate out the otherpkgs based on image
name. Being able to configure otherpkgdir is a good feature
that seems to work fine during genimage time - I would highly
encourage you guys continue with this feature and push it to
the otherpkgs postscript.

Take a look at this documentation , the otherpkgdir always
ends with the architecture directory and then the directories
under that contain the rpms. I have never seen anything
different so this may be a limitation in our code.
In other words in your case it should be

Subject: [xcat-user] xCAT ignoring my otherpkgdir setting
Hi all,
I am manually setting my otherpkgdir for an osimage that a node
belongs to. However when running "updatenode $node -S", the
setting is being ignored. The problem is bolded below.
Example is below, how do I get this thing to look at the right
path?
