bug#37851: Grub installation only checks for encrypted /boot folder

Hi again,

Attached can be found a workaround to mount all encrypted partitions.
There is no way to tell the devices to mount without changing
boot-parameters, where I'd add another field with the needed mapped
devices (a traversal onto the mapped-device dependency tree
of /gnu/store).  Do you think this is a good idea?  At least I think
it's the best way to encode the dependencies into the grub.cfg file,
even though the typical graph will contain 0 or 1 nodes.

Ideas?

Best regards,
Miguel
