Isn't better just to mount -t msdos /dev/xxxpn /mnt and cp /boot/loader.efi
/mnt/efi/boot/bootx64.efi?

If you have multiple boot environments: do you have a non-affected
BE (prior to c32dde3166922f55927764464d13f1bc9640f5f6)?<br>

So unfortunately i didn't have a recent BE, but I was able to do th=
e
following to get back up:<br>
<br>
1. download latest CURRENT snapshot memdisk from <a href=3D"ftp://ftp.f=
reebsd.org" target=3D"_blank">ftp.freebsd.org</a> and
put it on a usb drive<br>
2. boot via usb drive and enter live shell<br>
3. load zfs kmod:<br>
=C2=A0=C2=A0=C2=A0 kldload zfs<br>
4. import zroot:<br>
=C2=A0=C2=A0=C2=A0 zpool import -R /mnt/ zroot<br>
5. mount ROOT filesystem:<br>
=C2=A0=C2=A0=C2=A0 zfs mount zroot/ROOT/default<br>
6. copy usb loader to zroot:<br>
=C2=A0=C2=A0=C2=A0 cp /boot/loader /mnt/boot/loader<br>
<br>
<br>
i'd recommend just using boot environments, it's much easier an=
d is
specifically what they are for :)<br>
