I have two encrypted drives (one SSD for booting and a hard drive for storage) I need both to be unlocked and mounted before all of the runlevel programs/services. Else some of my services would freak out when they can't find my storage drive.
Currently, when I boot from my fully encrypted drive I get the following:
A password is required to access the root volume: Enter passphrase for /dev/sda1
What I'd like to happen is:
A password is required to access the root volume: Enter passphrase for /dev/sda1 Enter passphrase for /dev/sdb1
So I type in the key of /dev/sda1, then the key for /dev/sdb1 and then /dev/sdb1 is mounted. After this the system continues to boot.
