On the SSD storage cache thread there is a clear comment on the support for multiple encrypted disk unlocking on Qubes startup.
Running two disks each containing a different pool I have some problems when I am prompted for my decryption password. Problem is there is no identifying of which device I am unlocking and if I'm too late on the second device password or provide the wrong passphrase I better reset.
A potential walk-around would be to set the same password on both devices, but it's obviously not the best idea.
Is there a way for Qubes (or Xen?) to identify which device is being unlocked and load it upon decryption prompt?
