Since i started dual booting either Tiger or Leopard one thing that really annoyed me was that i had to deal with 2 itunes libraries , not being able to have the same thing in itunes no matter what i boot into.
Well there is a very elegant and easy fix for that that i am going to detail in this post and it only requires you to have a extra partition besides the ones that you are booting from.
So let’s get to it (texts in bold are shell commands and should be entered via Terminal):
1 – move your itunes library to a partition you do not boot from (i put mine on the Storage partition)
mv ~/music/iTunes /Volumes/IStorage/
2 – boot into each of the os’es and delete ~/music/iTunes if existing and make a symbolic link to the new location in its place
ln -s /Volumes/IStorage/Itunes/ ~/music/iTunes
This works beautifully and it works at some extent for things like Photo Booth too , also tho it might work i do not advise to make the links with Finder , just stick to console.
