[Koha-devel] etcdir & environment variables

[samst117+]

Three questions:

1.) how does one set up etcdir and environment variables? (since I will not be 
setting the system up as root)?

2.) How would you describe the location of each of these files/directories 
(since every system is set up a bit differently, I am having some difficulty 
establishing analogies between the example and the current system with which I 
am working --- yet another thing that needs to be patched in the documents [and 
which I would be happy to fix, after I have this system set up]:

ServerName koha.example.com
   ServerPath /var/www/library
   DocumentRoot /var/www/library/koha/html
   Alias /images/ "/var/www/library/koha/html/images/"
   ScriptAlias  /cgi-bin/koha/ "/var/www/library/koha/cgi-bin/"
   SetEnv PERL5LIB "/var/www/library/modules"
   ErrorLog /var/log/httpd/koha-error_log

3.) the same as the above question:  my directory looks like this:

/vservers/ireta/Library/koha-2.0.0pre2/

Yet I don't see an "opac" directory --- is this one of the places where the 
documentation is lagging behind? 

<VirtualHost 111.222.333.1>
    ServerName opac.example.com
    ServerPath /var/www/library
    DocumentRoot /var/www/library/opac/html
    Alias /images/ "/var/www/library/opac/html/images/"
    ScriptAlias  /cgi-bin/opac/ "/var/www/library/opac/cgi-bin/"
    SetEnv PERL5LIB "/var/www/library/modules"
    ErrorLog /var/log/httpd/opac-error_log
    #
    <Directory "/var/www/library/opac/html">
            AllowOverride None
            Options +Includes -FollowSymLinks -Indexes
            AddHandler server-parsed .html
    </Directory>
</VirtualHost>

Thanks!
