Consider not to delete named volumes by default when running system prune #31757
Description
Description
Consider not deleting manually named volumes by default when running docker system prune.
I now there is potentially a label filter coming soon but I am not sure that is enough.
A lot of people are using external named volumes with docker-compose and deleting those by default seems very risky to me.
Describe the results you expected:
By default only delete images without a manually given name.
Add a flag to delete all volumes, just like there is for images.
