 > Some more fundamental issues
 >   * I thought that the semantics of options_init_from_string were that
 it replaced the current configuration with cf_defaults+cf. But that
 appears to means that, in this code, the original torrc file is completely
 replaced with the first file in /etc/tor.d/, then by the second, then by
 the third, and so on.  (Is this tested?)

 I did not mean, if /etc/tor.d/10_something contains "CookieAuthentication
 1" and /etc/tor.d/20_somethingelse contains no line containing
 "CookieAuthentication", that /etc/tor.d/10_something is completely
 disregarded. The idea was that configuration fragments are joined together
 in a predictable order. (Bao, please see above.)

 >   * It seems that for an ordinary Tor user, there's no way to override
 this stuff.  If the system has an /etc/tor.d, I can't override those
 options even with "-f my_torrc", since the torrc is considered second, and
 the /etc/tor.d contents are considered last.  There is no way to override
 that directory with another one, either.  I don't think that can be the
 right way to do it, can it?

 This is a valid concern and no one considered that earlier. There is a
 solution.

 At the moment in the Tor manual (man tor), there is...

 -f FILE
 Specify a new configuration file to contain further Tor configuration
 options. (Default: $HOME/.torrc, or /etc/tor/torrc if that file is not
 found)

 and...

 --defaults-torrc FILE
 Specify a file in which to find default values for Tor options. The
 contents of this file are overridden by those in the regular configuration
 file, and by those on the command line. (Default: /etc/tor/torrc-
 defaults.)

 I suggest adding..

 --fragments FOLDER
 Specify a folder to contain further Tor configuration file fragments.
 (Default: $HOME/.tor.d, or /etc/tor.d/ if that file is not found)

 This should allow an ordinary Tor user to override it.
