Users would like to use a local cloud-config to modify how the resource/ephemeral disk is partitioned and where it is mounted on Azure VMs. Currently it seems this is only customizable via a configuration sent via CustomData (user data).

If I understand correctly, the Azure data source overrides the local cloud config for how this disk is set up. Users would like to be able to use a local cloud-config to override what's defined in the data source.
