13-CURRENT won't boot after switch to sysutils/openzfs

[marco]

I'm running r364030.

 [~] uname -apKU
 FreeBSD harbinger 13.0-CURRENT FreeBSD 13.0-CURRENT #5 r364030: Tue Aug
 11 07:15:59 UTC 2020
 root at harbinger:/usr/obj/usr/src/amd64.amd64/sys/GENERIC-NODEBUG  amd64
 amd64 1300105 1300105

When switching from base ZFS to sysutils/openzfs 2020080800 the boot process fails.

These are the steps I took:

- bectl create r364030-OpenZFS
- bectl mount r364030-OpenZFS /mnt
- edit /mnt/boot/loader.conf to use openzfs_load="YES" instead of zfs_load.
- bectl activate r364030-OpenZFS
- bectl umount r364030-OpenZFS
- shutdown -r now

The boot process shows:
Loader variables:
vfs.root.mountfrom=zfs:zroot/ROOT/r364030-OpenZFS

But in the end never boots and drops me to the mountroot prompt
I've tried several options to make it boot but when I just enter (empty
line) I get the following:

panic: mountroot: unable to (re-)mount root
