The new packages allow to boot, but I still have to enter the key twice,
once for each encrypted device.

Here they are:

/etc/fstab:
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
/dev/mapper/vg--ssd-root /               ext4    errors=remount-ro 0       1

/etc/crypttab:

sdb1_crypt UUID=9aa983b5-0224-406b-a177-7481162c6172
sda5_sdb1_common_key luks,keyscript=decrypt_keyctl
sda5_crypt UUID=3764df68-de26-4a24-a7dc-1498cb6b20ab
sda5_sdb1_common_key luks,keyscript=decrypt_keyctl


Note that the two partitions contain physical volumes for LVM, as shown
here:

  PV Name               /dev/mapper/sda5_crypt
