how can i map all users to root user using juicefs mount?

[lddlww]

i want to map all operation owner and group to root, like mkdir, chown, chmod, touch and so on, but i can't acheive it using follow command, root id is 0

 juicefs mount $METAURL -d /opt/containers/cloudsp/ --all-squash 0:0

above shows all owner is nobody and group is nogroup,

how can i do to solve it?

Currently, mapping to root is not supported. You can see related output in the initialization logs. This is primarily used for privilege de-escalation, not escalation.
