This is seen acutely in a Docker operation: https://dev.azure.com/azure-sdk/internal/_build/results?buildId=6163023&view=logs&j=8be16720-14eb-5bbb-1134-7a8b2c5000bc&t=a0c07037-a2d1-50ae-5f8b-6c944fe39137&l=76

To update:

1. Have docker store images/artifacts on the attached storage (default root storage is not terribly spacious)
2. (lower priority, defense in depth) Have Rust use the same attached storage. Something like CARGO_HOME
