I just installed redis on an Ubuntu server. When I examined its file permissions, I saw

-rw-r----- 1 redis redis 59124 Jan 11 02:24 /etc/redis/redis.conf

  1. Why does the redis user need write access to the conf file?
  2. Would it be more secure to change the permissions to -r--r-----? If so, what are the downsides (if any) to doing this?
