Comment 5 for bug 1577057

I was not at the machine yesterday to test but it is strange indeed. The system would never boot without re-importing the pool manually. It was 100% consistent.

When I noticed the rootdelay option still set, I removed it manually from the grub command line the first time, which worked. Then I adapted /etc/default/grub and updated grub to make it permanent. Since then, no more boot issues. That's when I went to check the initramfs zfs script.

I just tried it out quickly in a VM and I can't reproduce it there either :-/

I'll check this out tonight as now I'm really puzzled by this. Other than the rootdelay option nothing changed.
