Making this RC as initramfs-tools 0.130 landed into testing on May 1st,
and as of 2:1.7.3-3 the cryptroot hook doesn't detect resume devices
with the new logic from initramfs-tools >=0.129:

  * setting RESUME under in an initramfs-tools configuration file other
    than /etc/initramfs-tools/conf.d/resume isn't supported
  * setting RESUME=none yields a (harmless) warning
  * setting RESUME=auto (or leaving the variable undefined) might result
    into an unresumable device: the initrd is then configured to resume
    from the largest swap partition, which might not be unlocked in time
