plymouth doesn't say which luks passphrase it wants

[Mike Doherty]

I have two additional encrypted filesystems which are mounted at boot. For the first one, I'm prompted "The filesystem for $mount_point is unavailable... enter passphrase for /dev/mapper/encrypted_vol". Once the passphrase is entered, the text box empties, but no other text on the screen changes. I've deduced that this is the prompt for the second filesystem's passphrase, and indeed entering the passphrase at this time works. Boot continues, and both filesystems were mounted. But obviously, the text should change to indicate which filesystem is unavailable, and which volume to enter a passphrase for.

I've remembered the prompt incorrectly.

The first prompt is as I described. For the second prompt, the text saying which filesystem is unavailable does change. But plymouth still says "Unlocking the disk /dev/mapper/the_first_volume" instead of updating to reflect the volume that is really being unlocked this time.

I will upload a video shortly.
