RubyGems library is in charge where to install your gems. Here [1] is the logic and I am not touching it in this patch. That means only RubyGems library is installed into the custom location while the gems are installed into location specified by RubyGems.

It is good habit to place right content into right folders. You probably don't save your documents into /etc or /tmp just because you can. There are standards [2] which describes what should be placed where. It is definitely good idea to not intermix software installed by RPM and by you manually. Therefore there are different locations for that purposes.

Speaking as a Ruby maintainer of Fedora, it is definitely my responsibility to cultivate good habits and place software where it belongs. I understand that Ruby supports more OSes with different needs and different standards, therefore my patch does not change any defaults, but allow to support needs of my platform. Btw I am using Ruby also on Windows and there is definitely no need for such configuration option, but it definitely does not harm anybody.

Feature #5617: Allow install RubyGems into dediceted directory

Hello,

I would like to propose my patch, which allows to optionally install RubyGems library into dedicated directory, out of the default Ruby directory structure. This should enable to easily share one RubyGems library by more Ruby implementations and avoids code duplication. I did this patch since Fedora prohibits duplication of system libraries [1], which would be the case if MRI and JRuby are installed in parallel.

Thank you for considering this patch.

Vit
