Comment 26 for bug 1879980

I've managed to verify the initramfs-tools Focal-proposed package (version 0.136ubuntu6.3) by following 2 approaches, given that we don't have its cryptsetup counter-part released yet:

(a) The verification by "negation" aims to check if we don't have regression, by testing if the new package changed the old behavior. And it passed: with the proposed initramfs-tools, if we have a degraded RAID1 holding the encrypted rootfs, Ubuntu fails to boot exactly like using the regular/released initramfs-tools package, so no regressions/behavior-change introduced.

(b) I've tested with a modified cryptsetup package [0] that included the fix counter-part, and in this case, we are able to boot as expected, proving that the initramfs-tools proposed package is working as it should.

Also, the armhf autopkgtest regression mentioned in the above comment is no longer an issue, it's fixed (test was re-executed and succeeded - likely a flaky network case).
Hence, marking this bug as verified for Focal.
Cheers,

Guilherme
