Migrate primary disk (duplicate)

Interresting thing:
After all this (even restore), I launched sysinstall.
I went in the fdisk section, selected the right disk, the right slice and
pressed S (toggle bottable flags), then w (write changes) and q to quit.
Then I choosed the "Install the FreeBSD Boot Manager".
Now it works. It boots from the second disk.

I don't understand what went wrong in my script.
What do I forget?
Do you understand??

The dd/geom stuff shouldn't really be necessary, AFAIK.

Hmmm, are you sure restore doesn't write files in their absolute

Also, can you try running boot0cfg on the destination disk, as a final
step, before trying to boot from it?
