Unable To Load Alertmanager Config Given MacOS Big Sur Blocking /tmp/ Write Access

[Carmezim]

MacOS Big Sur does not allow write access to the root dir.

During validation of the alertmanager configs cortextool tries to write to /tmp/validate-configxxxxxx which is blocked by MacOS and fails with read-only file system.

Example:

ERRO[0001] server returned HTTP status 400 Bad Request: error validating Alertmanager config: 
mkdir /tmp/validate-config003623358: read-only file system  
fields.msg="error validating Alertmanager config: mkdir /tmp/validate-config003623358: read-only file system" status="400 Bad Request"

Is there a way to provide or modify the validation directory?

That is a cortex issue actually
