I've actually tried the command I posted above; seems to be working. 'consolidated.db' is symlinked to /dev/null just fine. I'm curious though, which part is erroneous? So I better understand for the future :p
1.) Encrypt your iOS device backups. You're crazy if you don't already have this checked.
2.) Wait for next iOS update to patch this.
3.) If #2 doesn't happen, then begin to worry.
The endless logging of location data looks like a bug.
My iPhone hasn't touched consolidated.db since I last used Google Maps. It is still at the exact same size as it was before. So clearly you can turn it off somehow.
untrackerd routinely wipes iPhone location data on jailbroken iPhones from Cydia.
