I think I have made some progress but I still have two questions.

Is this safe to make
offset of swap within wd1 >= offset of raid0b + RF_PROTECTED_SECTORS
so that a kernel dump won't erase filesystem data?

The wd1 disk on the guide has 1008 sectors/cylinder.
But when it is relabeled (15.3.7. Setting up kernel dumps)
the swap area is at offset 19015807 which is not at a cylinder boundary.

I didn't find a way to make my disklabel accept that.
How can I do that? Is it safe?

Thierry.
