OK, thanks. That explains why/how I lost some changes to a mysql database a while back when I upgraded OS versions...
Do you know whether it is possible to share the databases themselves WITHOUT sharing the MySQL installation? It would seem to be useful to be able to upgrade MySQL versions on the safety clone without affecting the main drive, just in case...but I see no reason to not share the databases themselves.
Similar question for PHP...since PHP comes preinstalled on OS X, is that a shared directory so that when I upgraded PHP versions it affected a shared copy? Now that I think about it, when I installed PHP5 I think it created a new PHP5 directory, which, presumably, only exists on the safety clone. Am I correct?
Another question...spotlight does not do a good job (in fact, ANY job) of locating files/folders inside the system....is there a way you know of to search for such folders so I can see what is there?
Final question: If I'm in terminal, is there any way of knowing if I'm following a symbolic link when I navigate around the directory structure to see if I'm on the safety clone or the main drive?
Thank you again for your help.
