Removing from Solr 10.0 the -c option is a stumbling block for any number of scripts. SOLR-18269: Restore -c as a no-op function for bin/solr start, https://github.com/apache/solr/pull/4473 proposes adding it back as a no-op function with a warning if you DO provide it. Hopefully this takes some of the pain away from starting Solr Cloud clusters. Unfortunantly won't be released till 10.1. Eric
