I have installed Tor on Ubuntu 14.04 according to instructions at https://www.torproject.org/docs/debian.html.en
I got the basic relay configured and working but I have file permission issues with file permissions of a hidden service private_key and hostname files. Tor is started as root, it will do some magic and then it drops itself to run as "debian-tor".
File permissions:
sudo ls -l /home/debian-tor /home/debian-tor/tor_keys =>
/home/debian-tor:
total 4
drwx------ 2 debian-tor debian-tor 4096 Jul 17 10:59 tor_keys
/home/debian-tor/tor_keys:
total 8
-rw------- 1 debian-tor debian-tor 23 Jul 17 10:59 hostname
-rw------- 1 debian-tor debian-tor 891 Jul 16 17:52 private_key
Starting as a service (does not work):
sudo service tor start =>
[notice] Tor 0.2.6.10 (git-71459b2fe953a1c0) opening new log file.
[warn] Could not open "/home/debian-tor/tor_keys/private_key": Permission denied

Starting from command line (works!):
sudo tor =>

Test to have an other user own the files (this shows that tor is really running as debian-tor):
sudo chown -R ubuntu_user:ubuntu_user /home/debian-tor
sudo service tor start =>

Trying to get Tor re-create keys:
sudo rm -r /home/debian-tor/tor_keys
sudo service tor start =>
[notice] Tor 0.2.6.10 (git-71459b2fe953a1c0) opening log file.

[err] set_options(): Bug: Acting on config options left us in a broken state. Dying.
Running sudo tor would create the folder and write hostname and private_key files there.
So my question is how could I get sudo service tor start working? It somehow does not have root nor debian-tor privileges to write there, or maybe I am missing something. Or should I just not use the /etc/init.d/tor script to manage it?
