[Bug 251164] Re: boot impossible due to missing initramfs failure hook / event driven initramfs

[Guilherme G. Piccoli]

This is a somewhat old LP bug, but for completeness it worth mentioning
here that recently some patches were merged on initramfs-tools and
cryptsetup, that allow a good experience booting with LUKS-encrypted
rootfs on top of a degraded RAID1 array; for details, please check:

Cheers,


Guilherme

Title:
  boot impossible due to missing initramfs failure hook / event driven
  initramfs

Status in cryptsetup package in Ubuntu:
  Triaged
Status in mdadm package in Ubuntu:
  Confirmed

Bug description:
  the cryptsetup package needs proper integration into the initramfs
  failure hooks

  The system must not assume a particular layered setup or sequence of
  appearance of (hotplug/udev/crypt/md/degraded-md/lvm) devices.

  It must be able to boot with any possible combination raid, lvm, crypt
  combination that the debian-installer can produce.
