Here are the steps I needed to start elasticsearch.service:

1. Corrected Keystore Ownership: Changed the owner of /etc/elasticsearch/elasticsearch.keystore from root to elasticsearch to allow the service to access it.

2. Updated JVM Options: Modified /etc/elasticsearch/jvm.options to use an absolute path for GC logs (/var/log/elasticsearch/gc.log), resolving a "Permission denied" error when the JVM attempted to write to the working directory.

3. Configured Explicit Paths: Added path.data: /var/lib/elasticsearch and path.logs: /var/log/elasticsearch to /etc/elasticsearch/elasticsearch.yml. This prevents Elasticsearch from attempting to create data and log directories within its installation home (ES_HOME), where it lacked the necessary write permissions.

This patch adds symlinks for all executables in /usr/share/elasticsearch/bin into /usr/bin.

No functional changes to the packaged software, only improved accessibility of bundled tools.

Please consider merging this change. Thank you!

Unfortunately, installing the latest version breaks indices created with previous versions:

fatal exception while booting Elasticsearch java.lang.IllegalStateException: cannot upgrade a node from version [8.17.4] directly to version [9.0.2], upgrade to version [8.18.0] first.

8.18.0 is not available in the AUR, so, unless you are ok with discarding your indices, you will need to manually download it from the Elasticsearch website and install it.

They probably do not have to be

Why are all config files executable?

The package still refers a lot to /opt/elasticsearch, and makes it hard to use ...

Thanks @ipaqmaster. I've added the patch.

The below diff seems to do the trick but this package has other problems. Everything keeps referring to /opt/elasticsearch including /opt/elasticsearch/bin/elasticsearch-keystore create but the service itself runs pointing to /etc/elasticsearch. May be a good idea for this package to take some of the config from https://aur.archlinux.org/packages/elasticsearch to help streamline the installation.
