zfs send results in cannot mount '/': directory not empty #346

Hello!
I'm talking about this guide

Although the following zfs create command does not return errors:
zfs create -o acltype=posix -o atime=off -o compression=zstd-3 -o checksum=blake3 -o dnodesize=auto -o encryption=on -o keyformat=passphrase -o overlay=off -o xattr=sa rpool/ROOT

The following command will error with cannot mount '/': directory not empty
zfs send -R rpool/copyroot/pve-1@copy | zfs receive -o encryption=on rpool/ROOT/pve-1

So I used:
zfs create -o encryption=on -o keyformat=passphrase rpool/ROOT

And then zfs send works properly.

Notice that when using the zfs create command for the rpool/data there are no issues
