 ### I added an additional disk with partitions. Why is it not getting detected?

+### How to add ssh authorized keys to a Harvester node using a modified config file?
+
+Option 1. Non Persistent (Temporary)
+To dynamically add users in the runtime without rebooting, add ssh authorized keys to /home/rancher/.ssh/authorized_keys. These changes are not persistent between reboots.
+
+Option 2. Persistent
+After you ssh login to Harvester, add ssh authorized keys to your /oem/99_custom.yaml or 90_custom.yaml. These changes are persistent between reboots.
+After you modify your cloud-init script, reboot the node to see the changes take effect. 
+See [Cloud-init support - stages.STAGE_ID.STEP_NAME.authorized_keys](https://rancher.github.io/elemental-toolkit/docs/reference/cloud_init/#stagesstage_idstep_nameauthorized_keys) for details on adding ssh authorized keys to a config file.
