Comment 51 for bug 1879980

1) There are no changes with the cryptsetup in bionic-updates.

This is expected, because the changes in initramfs-tools
are gated by a file introduced in the patched cryptsetup.

Thus no regression from the initramfs-tools side.

...

And, additional testing with the _patched_ cryptsetup,
just in case so that we've it tested if/when it lands.

2) It works correctly with the patched crypsetup from PPA.

This validates that the changes in initramfs-tools work
as intended when paired with the new cryptsetup changes.

2.1) There are no changes in the good path/case
i.e., RAID is not degraded, user enters correct password.

2.2) There is one more iteration to ask password 3 times.
i.e., RAID is not degraded, user enters incorrect passwords.

- original behavior: 2x iterations of asking password 3 times
- modified behavior: 3x iterations of asking password 3 times

2.3) It can boot in the bad path/case
i.e., RAID is degraded, user now can enter password and boot.

- original behavior: times out in 180 seconds in local-top,
  checking LVM every 10 seconds, then drops to shell.

- modified behavior: times out in 5 seconds in local-top,
  moves on to local-block, checks for 30 seconds every 1
  second (including LVM); md/raid activated in 20 seconds.
  (asked for password and booted successfully.)
