not asked for encrypion passphrase when booting encrypted drive after upgrade to 15.0

[Poldi]

 I've had '/' and '/home' on two separate encrypted drives and was always prompted for both passphrases during boot prior to upgrading.

After upgrading to 15.04, I'm only prompted for the '/home' drive.

Following is the the fstab file, the /dev/mapper folder and the result from df

Thanks

Leo

 I did the following and the result seems to indicate that "/" "/home" and swap are encrypted.

Question is why is df not showing "/" and swap as "/dev/mapper/sda...." and why am I not prompted for the password for "/"

Added a copy of the boot log

Just realised after the last boot the the device I get is sda_2 which is "/", not "/home" as stated in the initial post.
