Rebasing with Subversion

In git the rebase command is pretty useful when you want to get your own changes on top of whatever happened on master (or trunk as it is called in subversion land). But how do you do this in subversion? And safely? The closest I came to something similar is working on a feature rebase branch. So given trunk and a feature branch I’d do something like this:

svn cp trunk feature-branch-rebase

cd feature-branch-rebase
svn merge feature-branch 
# resolve all the conflicts, build the thing, run the tests and so on
svn commit
# let it run on the build server.... 

cd trunk
svn merge feature-branch-rebase
svn commit

This last merge should then be trivial and not cause any headaches on trunk….
