ROCKS7: Modify behavior and/or update docs for custom partitioning

tcooper commented 7 years ago

Order is important...

Rocks7 custom partitioning cannot be done in extend-<node>.xml and possibly in replace-<node>.xml due to new installation behavior related to Anaconda in CentOS 7.

Example solution is to splice onto the graph with custom graph & node XML...

/export/rocks/install/site-profiles/7.0/graphs/default/compute-partitioning.xml

<?xml version="1.0" standalone="no"?>

<graph>

<edge from="compute" to="compute-partitioning"/>
<order head="compute-partitioning" tail="partition"/>

</graph>

/export/rocks/install/site-profiles/7.0/nodes/compute-partitioning.xml

<?xml version="1.0" standalone="no"?>
<kickstart>

<pre>
cat &gt;&gt; /tmp/user_partition_info &lt;&lt; 'EOF'
clearpart --all --initlabel --drives=[device_name]
zerombr
part / --fstype=ext4 --size=65536 --ondisk=[device_name]
part /scratch --fstype=ext4 --size=1 --grow --ondisk=[device_name]
EOF
</pre>

</kickstart>

Where [device_name] is sda or vda or other raw block device detected during install.

Thanks, Trevor. The most likely fix will be:

define a node in the base graph called custom-partition.xml
have the base graph define the order custom-partition --> partition
modify docs to suggest extend-custom-partition.xml as the place to insert custom partition code

Partially completed. Latest version has custom-partition. Docs haven't been modified yet.
