Ok. So with these suggestions, I found https://lucene.apache.org/solr/guide/6_6/configuring-solrconfig-xml.html#Configuringsolrconfig.xml-ImplicitCoreProperties So to test this I tried to use it in DIH as this has a similar issue with configsets as every collection needs its own DIH.properties.
<propertyWriter dateFormat="dd-MM-yyyy HH:mm:ss" type="SimplePropertiesWriter" directory="/var/solr/data/${solr.core.name}/conf" filename="DIH.properties" locale="nl-NL" /> However does not work. Substituting ${solr.core.name} with core name, does work. Am I missing something? -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
