passengerでALB2のURL Rootを/alb2にかえる

http://guides.rubyonrails.org/v4.0.6/configuring.htmlによれば、
config.action_controller.relative_url_root can be used to tell Rails that you are deploying to a subdirectory. The default is ENV['RAILS_RELATIVE_URL_ROOT'].
とかいろいろ調べてやったが、結局 rails4.0 + hobo2.1ではsubdirectoryは成功せず。

redmineではうまくいく。しかし、redmine 2.5は、rails3.2ベース。redmineのconfigurationの変更は一切不要だった。rails4の問題かも知れないが、rails4.1ベースはredmine 3でまだリリースされてない。

relative URL rootのためのapache2のconfファイルの例:
<VirtualHost *:80>
ServerName alb-server

DocumentRoot /var/www

<Directory /var/www>
Allow from all
Options -MultiViews
</Directory>

Alias /alb2 /home/anagix/work/alb2/public
<Location /alb2>
PassengerBaseURI /alb2
PassengerAppRoot /home/anagix/work/alb2
</Location>

<Directory /home/anagix/work/alb2/public>
PassengerRuby /opt/rubies/2.0.0-p481/bin/ruby
Options FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
Options -MultiViews
</Directory>

Alias /redmine /home/anagix/work/redmine/public
<Location /redmine>
PassengerBaseURI /redmine
PassengerAppRoot /home/anagix/work/redmine
