[tor-dev] can tor use secondary groups to read FamilyKeyDirectory?

Hi,

given the following example, tor fails to access the familykeydir folder.

familykeydir has the following permissions:

drwxr-x--- 2 root tor_reader

id _tor uid=996(_tor) gid=993(_tor) groups=993(_tor),994(tor_reader)

Is tor able to use secondary groups?

When using sudo to switch to user _tor manually, it is possible to read files in that folder without problems.

The problem does not happen when _tor's primary group is set to 'tor_reader'. Tested on debian.

kind regards, nusenu
