[Chimera-users] installing chimera over an older chimera install?

Hi, On *nix is it safe to install a newer version of chimera over a previous installation? Will this break something in the newer installation? The reason why I ask is the trouble of maintaining externally installed plugins. We could make a wrapper for the .exe unzipsfx install and re-build symlinks to an external directory of chimera plugins in the share directory, but this seems like too much trouble especially if just installing over an old installation should just "work". Thanks, Sabuj
