[pkg-cryptsetup-devel] Boot Debian Buster with encrypted root on degraded raid1 (md-raid)

[Magnus Sandberg]

Hi Guilhem,

Thanks for your reply. I sent my original post (more or less) to 
submit at bugs.debian.org according to the web page recommendations for 
pseudo-headers. This will be a new experience for me :-)

Regards,

Thanks for your contribution!  But unfortunately the messages sent to
this list are likely to be overlooked if there is no bug report to it.
Could you please file a bug against the ‘cryptsetup-initramfs’ package?
(cf. https://bugs.debian.org ).  Otherwise I'll do it myself.

I'm unsure about this, mdadm's local-block script may delete the count
file, and local_device_setup() has a more complex logic around calling
the script.  Perhaps we should use that to work array degraded modes.
Anyway for the sake of transparency, the discussion belongs to a bug
report :-P
