They don't need to be mounted to be in the by-uuid directory.  It's just 
an association from uuid's to device files.  Looks something like this:

lrwxrwxrwx 1 root root 10 2009-04-02 05:58 
5973158c-b58c-496a-af16-9355ab5b2286 -> ../../sda3
lrwxrwxrwx 1 root root 10 2009-04-02 05:58 
731651fc-b3e5-4260-a7ed-6784fc668450 -> ../../sda2
lrwxrwxrwx 1 root root 10 2009-04-02 05:58 
8a237b1d-0ba2-43b2-b813-b906d7723edf -> ../../sda4
lrwxrwxrwx 1 root root 10 2009-04-02 05:58 B4EE1D64EE1D1FE2 -> ../../sda1
