I’m really interested in Haiku, and I’d like to contribute to the project. So… My question is simple. What part of the repository should I checkout?
The whole svn://svn.berlios.de/haiku/?
The trunk svn://svn.berlios.de/haiku/haiku/trunk/?
The most important difference for you is that you don't want to check out the entire repository anymore: unlike CVS, Subversion would leave you with all tags and branches as separate files on your hard drive - which totals in about 1.4 GB of files at the moment. Instead, you will specifically ask for the "trunk" only - that's what you already know as the CVS root now.
To get a copy of the current Haiku tree (and Haiku only), you would write something like this:
svn checkout svn://svn.berlios.de/haiku/haiku/trunk [directory-name]</blockquote></div>
