            Bug ID: 254152
           Summary: [zfs] rewind does not work on boot zpool
           Product: Base System
           Version: 13.0-STABLE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: standards
          Assignee: standards@FreeBSD.org
          Reporter: zlei.huang@gmail.com

I'm exploring the new feature introduced by https://reviews.freebsd.org/D24=
920
, but without success. There're lots of `Solaris: NOTICE: Cannot find the p=
ool
label for '!zroot' ` in console log, and the boot end up with `Mounting from
zfs:!zroot/ROOT/default failed with error 5. `. Manually input
`zfs:zroot/ROOT/default` in the mountroot prompt then it boots successfully=
 but
checkpoint of the zfs pool zroot keeps untouched.

Environment:
A Fusion 12.1.0 VM with 4 processor cores and 2G memory, an 4G NVME disk,
firmware type BIOS .

Steps to repeat:
1. Fresh install FreeBSD 13.0-RC1
2. Boot and login with root user and make a checkpoint, zpool checkpoint zr=
oot
3. Reboot, and toggle the option `Rewind ZFS Checkpoint` Yes in the bootloa=
der
menu
4. Enter to boot, and the boot end up with errors.=20

Expected behavior: The boot should succeed and the zfs pool should be rewou=
nd
upon succeed.
