#26913: DataDirectoryGroupReadable enabled does not have effect
------------------------------+--------------------------
Reporter: maha | Owner: (none)
Type: defect | Status: new
Priority: Medium | Milestone:
Component: Core Tor/Tor | Version: Tor: 0.3.3.9
Severity: Normal | Keywords:

------------------------------+--------------------------
On RedHat based systems the defaultrc includes DataDirectoryGroupReadable
set to 1. But when starting up the daemon this is ignored and chmod of
/var/lib/tor is set back to 0700.
This can be demostrated by the following test using vagrant:
{{{
