So, my question is : is there a linux flavour that processes the package installation in a efficient way, installing only the common files among the packages instead of copying them all ?
No, install the files by hand from .tar.gz
Some say "linux is free".
I say linux "linux is free ... as long you don't have to buy a new 17 ou 19 inches monitor and a bigger hard disk" :pissed:
Linux is free if your time has no value.
