Comment 2 for bug 1867007

This bug was fixed in the package zfs-linux - 0.8.3-1ubuntu10

---------------
zfs-linux (0.8.3-1ubuntu10) focal; urgency=medium

  [ Jean-Baptiste Lallement ]
  [ Didier Roche ]
  * Make debian/patches/4000-zsys-support.patch more robust in case of
    corruption and faster:
    - Don’t call out zsys if the system hasn’t changed compared to its cache.
      This drastically speed up boot by some seconds.
    - Drop into emergency mode with some error message in dmesg with the
      failing command output in case some errors happen during revert.
      Prevents thus booting which would have screwed over root partition by
      creating a /boot non empty directory (like /boot/grub) in mounting over.
      Let now user still boot without reverting to be able to fix the issue.
    - Base what we import on cache file so that in the future (once grub is
      fixed) booting with multiple rpool and bpool. (LP: #1867007)
  * debian/patches/4500-fix-generator-invalid-cache.patch:
    - Removed, not needed anymore with previous patch enhancement.
