Comment:

 Yes, please.

 The Debian service file still needs to give tor the CAP_DAC_READ_SEARCH
 capability (which lets uid 0 override DAC file permissions for read/search
 purposes) or else it falls flat on its face with hidden services (cf.
 [https://bugs.debian.org/847598 Debian#847598]).  We'd appreciate if Tor
 did not need this elevated capability.
