Bug Description
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.

The mount location can be reconfigured in the waagent.conf file, after provisioning of the VM.
A shut-down and start-up sequence is required, in order to let the changed settings become effective.
It is not desirable and/or advisable to change partitioning and/or mount locations on creation time.
It is also not desirable and/or advisable to change partitioning of the resource (ephemeral) disk, given the fact that this disk is not really intended for persistent data storage and the fact that one minor change in settings (changing ResourceDisk. Format= n to ResourceDisk. Format= y) will result in a loss of all data and partitioning settings (!).
When requiring a (persistent) data disk, please attach an additional data disk (with all freedom available, for custom configuration of partitioning and/or mount points).
Kind regards....
