I found the following problem. When I updated the contents of data/dataURL file to complain with the new class names at v2.3 I found that they were not having any effect.
This is because startup.cpp will copy that file to the user space at $HOME/.rest/ if it does not exist already. In the next make install, at the installation location /install/path/data/dataURL this file will be updated. However, it won’t be updated at the user space that is the one that is really used.
So, do we need this file really to be at the user space? If so, then startup.cpp should checksum and if any differences it should update, I guess.
