Description

Currently a-d-c sends a bash script to new cloud instances (as "CustomData" on Azure, "UserData" on EC2) in order to stash a secret string on the instance, which is checked upon first SSH connection as an alternative to verifying the instance's SSH host key fingerprint.

This proposed feature would allow the operator to use the CustomData/UserData feature for additional instance setup tasks.

  CloudVMs:
    InstanceInitCommand: "echo ok\nexit 0\n" 

This command/script, if configured, would be appended to Arvados's existing builtin bash script.
