On some OS:es you have to reboot sometimes. Upgrading, security fixes ...

But there is another difficulty too. If the user happens to give the 
wrong answer when prompting for the directory then it is hard to find 
out how to change it. Maybe there should be a simple sanity check? This 
could be at the prompting or (better I believe) when trying to access 
the sources. Then a new prompt could be issued.
