boot0cfg

[Dick Hoogendijk]

  I dumped/restored the system to ad8 yesterday and booted from it.
The system *did* boot but (alas) the /dev/ads1a(f) slices were mounted. 
So, the system loaded the *old* root partitions (from the first drive). 
After googling and reading I think I need *boot0cfg* but I'm a bit scary 
to ruin my new boot (ad8) drive.

So, what is the exact syntax to make my system not only boot from ad8, 
but also mount the /deb/ad8s1 slice as root slice?

Hope to get some answers.
