Bug description:
[Impact]
In the event of a loss of power, ext4 filesystems mounted w/
data=journal,journal_checksum are subject to a corruption issue that requires a
fsck to recover. This is exacerbated by installations by curtin that set
passno=0 in /etc/fstab, preventing fsck from running automatically and thus
requiring a manual recovery. And *that* is further exacerbated because
initramfs-tools is smart enough to not include fsck.ext4 when passno=0 is
detected in /etc/fstab, requiring the user to boot from recovery media.
[Test Case]
Forcibly power cycle a system running 'stress-ng --dir 0'. I've created a
package to automate the reproduction:
