I considered that option, but was somehow uncomfortable about
it... Maybe the fact that debian's default is 022 made me cautious, or
I wanted to know if there was an alternative before changing a system
wide default. It feels strange to modify a system's default config
just for one directory, but it seems I have no other choice (except
creating a fat32 partition and mounting it with the right
parameters... :-) 

Now why is debian's default 022 if 02 is safe ?

Thanks for your answer,
