I can't get past a kernel panic on boot. Maybe I should have waited longer
before I cut the power to the complete system, to allow Raid to sort itself
out. I suppose I might be able to rescue the system with a rescue setup
running off a ram disk, but it's simpler to do the lot from scratch again.
This experience has made me think - it's no great hardship for me, I'm just
a hobbyist fiddling around with configurations that interest me. But I'd
think again before jumping into software raid for a serious setup.
