# Enhancement Currently we can only supply a [Universal Disk Format (UDF)](https://en.wikipedia.org/wiki/Universal_Disk_Format) iso to the [Azure data source](https://github.com/canonical/cloud-init/blob/26.1/cloudinit/sources/DataSourceAzure.py#L2066-L2067), but that should be generally available to all data sources. All the places that currently search for iso9660 disks should also look for udf disks.
