First, I propose:

That would be an adaptive approach.  Any kickstart directive can be slurped up 
through %include.

This is what I would suggest.

I’m not familiar with the partition directive.  I personally tend to favor just 
putting a copy of template in 
/install/custom/install/rh/profilename.rhels7.tmpl if I have to customize.

In your case, if it’s just about proper ignoredisk, I’d just do the above.

Someone else can probably speak to why that look iterates through a plurality 
and then just pays attention to the last one.  I also see no evidence that 
anything but the last matters.

In file:
on line: 189
it appears that a partition file (value) can effectively specify multiple files 
by separating the filenames with commas.
However, the following foreach doesn't do anything with the multiple values 
except walk through them and keeps only the last value.

Am I missing something?

Is this perharps a hook for new functionality that is not yet finished?

I think I figured out what's going on (and for posterity sake I will 
elaborate.) Anaconda never uses the provided kickstart directly, it always 
creates it's own kickstart file.  The kickstart provided by xCAT simply 
provides answer to Anaconda just like the interactive GUI or text install 
configurator would provide (I would guess that Anaconda doesn't even know how 
it got the answers, whether from kickstart or GUI or text configurator.)  
Anaconda then runs any "%pre" sections, slurps in any "%include" files, and 
probably other stuff, then sanitizes all the data and creates the actual 
settings file it uses for the install, which is saved in /root/anaconda-ks.cfg.

As Jarrod suggests, I simply need to get my own "ignoredisk --only-use" line 
into the kickstart so that Anaconda does not add it's own.  I tested by 
hardcoding the line directly in 
"/opt/xcat/share/xcat/install/centos/compute.centos7.tmpl" and indeed Anaconda 
did not add it's own ignoredisk directive.  I do not want to hardcode the "sda" 
value, so would like to make it a little more dynamic.

However, if I provide my own script to osimage.partitionfile, the default xcat 
partition script output is not included in the kickstart.

In the simplest of terms, what I need is "ignoredisk --only-use=$instdisk" in
Is there a way to access $instdisk in my own script?

Or, is there a (clean) way to get both "%include /tmp/partitioning" AND 
"%include /tmp/partitionfile" in the xcat generated kickstart file?
This latter idea would allow me to output something like "ignoredisk --drives=" 
for anything that should not be touched by the install.  Then everything else 
could work normally.

If explicit, it should use that over any calculated value.

Subject: [xcat-user] kickstart wipes out partitions of all local disks

xCAT Version 2.11.1
Lenovo X 3550
CentOS Linux release 7.2.1511 (Core)

On a stateful install, both sda and sdb are wiped, even though the kickstart 
correctly identifies and paritions (and installs to) sda.  The 
/root/anaconda-ks.cfg file on the freshly installed node includes these lines:

> ignoredisk --only-use=sda,sdb
> zerombr
> clearpart --all --initlabel

which I suspect are the issue.

However, I can't figure out how the "ignoredisk" line got in the kickstart or 
from where it came.  It have verified that it is not in any of the xCAT 
templates or "pre" scripts, nor is it in the xCAT generated 
/install/autoinst/<nodename> file.

All xCAT settings relating to storage and partitioning are default.  The 
osimage does not have a custom partitioning script associated with it.

Does anyone know where this comes from or how it gets put in there, or, more 
importantly, how to work around it or adjust it?
