Fixing Grub on a ZFS install

I've built an arch install on top of a ZFS root, which has worked for a while, but now I'm having some issues booting. This started when I added

net.ifnames=0

to /etc/default/grub, and then ran grub-mkconfig. I cannot remember now whether I got errors at that stage, but upon rebooting I'm greeted with the following:

GRUB loading...
Welcome to GRUB!

error: no such device: 34a210a061e85c2c
error: unknown filesystem.
Entering rescue mode
grub rescure>

From the live environment, I rolled back to a previous snapshot, such that my entire /boot directory was consistent with it's state a week ago. This produced the same results.

I also tried re-installing Grub. grub-install finishes without error, but mkconfig produces the follow results:

[root@archiso /]# grub-mkconfig -o /boot/grub/grub.cfg 
Generating grub configuration file ...

done

It should be noted that I am NOT using lvm, ZFS is handling sda-sdf. sdg is the live USB.

Not an Installation issue, moving to Apps and DEs...
