As others have said, this is by design. If you want to do sparse
checkouts, or platform-specific checkouts, the only way that I know of
is to use svn switch. The pattern is that you make an empty
"placeholder" directory in the repository for something that is not
always checked out, or checked out differently in different
circumstances. Then you svn switch that directory to some other
directory in your repository. It pretty much forces you to do your
checkouts using scripts, but you can put self-describing metadata (svn
properties) in the repository directories that let you keep the details
in the repository itself. I have just finished implementing this and it
really works pretty well. After you check out, you can use a SVN GUI
client to manage the tree (smartSvn, for instance), or just command line
svn.
I searched around a lot when I was moving from a CVS repository (that
only used modules for checkout) to a new SVN repository. I found this
technique in a message that I think was on the SVN users list, posted by
someone from Collabnet. He said that they use this method internally.
