Folks,

This is a comment on the following important bug report:

The last sentence caught my eye first. This is not supposed to  
happen, so I immediately tested. On my machine, installing  
TeXLive-2007 left the old /2006 directory intact. and the TeXDist  
Preference Panel saw both TeXLive-2006 and TeXLive-2007 and let me  
choose between them. I could typeset a large LaTeX document with  
either distribution. Inspecting the console showed that the correct  
distribution was being used in each case.

There is nothing in the MacTeX package which would remove files. No  
"rm" command is present in the pre- and post-install scripts, and the  
command which installs files adds missing files and writes updated  
files, but doesn't remove anything.

Thus I think Bruno's experience is due to some other cause. 'll  
respond immediately if contrary evidence develops; feel free to call  
directly in the middle of the night!

The second and third paragraphs from Bruno are also important and  
I'll investigate further. Texhash is not currently called by the post- 
install script, but such a call could easily be added.
