DataDirectoryGroupReadable does not take effect when relay enabled
Add 'DataDirectoryGroupReadable 1' Permissions on /var/lib/tor are as expected: 0750
Now, uncomment 'ORPort 9001': Permissions on /var/lib/tor briefly switch to 0750 but then back to 0700, despite DataDirectoryGroupReadable being still set to 1.
The patch for Ticket #17562 (moved) that adds DataDirectoryGroupReadable option did not change all calls to check_private_dir: https://trac.torproject.org/projects/tor/attachment/ticket/17562/0002-Introduce-DataDirectoryGroupReadable-boolean.patch
Patch that fixes the issue is attached to this ticket. But, ideally, should factor the check for data dir into a function, but I figured a dev can do that instead of me dabbling with the code.
