I noticed that if you crypt your /home partition and start with the default
quiet splash parameters, you don ´t see the system actually asking for the decryption passphrase. Instead, the splash screen keeps on spinning as if boot is still processing. Note that at this time, you can blindly type in your passphrase and hit Enter anyway, and it will work, but it's kinda missing a prompt.
I noticed this behaviour on both xfce and KDE dragonized versions, and removed the
quiet splash parameters from grub so I'm fine, but new users willing to secure their documents might think the install is broken
