[pkg-cryptsetup-devel] Bug#933059: Debian Buster with encrypted root on degraded raid1 (md-raid)

[Guilherme G. Piccoli]

Hi Magnus, Markus and Javier - thanks for the reports, and special
thanks Magnus for the patch.

I've came up with a different approach [0] - initramfs-tools provides a
retry mechanism in which scripts are able to run multiple times on
local-block stage. The mdadm script that implements such "poor man's
last resource" (i.e., the degrading array assemble) runs in local-block
stage, but cryptroot fails right upfront in local-top, preventing mdadm
scripts from starting the array.

My approach (patch attached here) relies in changing cryptroot in order
it fails gracefully on local-top and allows local-block script to run.
It'll then be executed itself on local-block, and decrypt the volume
successfully.

Test results with my patch and reviews are greatly appreciated!
Cheers,


Guilherme
