Hi All,
I'm aware that many people are reluctant to use drslib because of it's use of symbolic links when constructing the DRS directory structure. I completely understand caution when using symbolic links but I wanted to make the case for why I believe it is necessary to meet the goals of a consistent distributed and versioned archive. Therefore I've prepared a wiki page that goes into the technical details:
http://esgf.org/wiki/DrsVersionLinking
Please read it carefully if you are currently considering how to implement the DRS directory structure. I propose we discuss this at the next ESGF telco.
Thanks,
Stephen.
