When I run `./bin/phd start`, it will try to sudo to the `phd` user, but fail:
```
Freeing active task leases...
Freed 0 task lease(s).
Starting daemons as phd
Launching daemons:
(Logs will appear in "/var/tmp/phd/log/daemons.log".)
PhabricatorRepositoryPullLocalDaemon (Static)
PhabricatorTriggerDaemon (Static)
PhabricatorTaskmasterDaemon (Autoscaling: group=task, pool=4, reserve=0)
sudo command failed. Starting daemon as current user.
Done.
```
I am unsure why that happens - `root` (the current user) should be able to sudo to `phd` ( I can definitely run `sudo -u phd ./bin/phd start` manually, without any signs of failure). `/var/tmp/phd/log/daemons.log` is empty. How would I debug this?
