Comment:
With `bdev_allow_write_mounted=true`, the behavior is as before.
Without it, it prints the same message
```
fsck.ext4: Device or resource busy while trying to open /dev/mapper/cryptroot-root
Filesystem mounted or opened exclusively by another program?
```
and then it continues (without fsck-ing other partitions like /boot).
So this seems to work as expected in my simple setup.
