  cryptsetup (2:2.2.2-3ubuntu2.3) focal; urgency=medium

  * Introduce retry logic for external invocations after mdadm (LP: #1879980)
    - Currently, if an encrypted rootfs is configured on top of a MD RAID1
      array and such array gets degraded (e.g., a member is removed/failed)
      the cryptsetup scripts cannot mount the rootfs, and the boot fails.
      We fix that issue here by allowing the cryptroot script to be re-run
      by initramfs-tools/local-block stage, as mdadm can activate degraded
      arrays at that stage.
      There is an initramfs-tools counter-part for this fix, but alone the
      cryptsetup portion is harmless.
    - d/cryptsetup-initramfs.install: ship the new local-bottom script.
    - d/functions: declare variables for local-top|block|bottom scripts
      (flag that local-block is running and external invocation counter.)
    - d/i/s/local-block/cryptroot: set flag that local-block is running.
    - d/i/s/local-bottom/cryptroot: clean up the flag and counter files.
    - d/i/s/local-top/cryptroot: change the logic from just waiting 180
      seconds to waiting 5 seconds first, then allowing initramfs-tools
      to run mdadm (to activate degraded arrays) and call back at least
      30 times/seconds more.
