I _know_. This guide was first mentioned by me in this thread.
But it assumes

- install
- boot
- create mirror on second disk
- copy data
- reboot
- sync mirror

Now Joao said, creating a mirrored disk can be done from
the "emergency holographic shell" at install time. OK, fine.
Spares the copying.

My question was: can I create a mirrored slice instead of
a mirrored disk without copying the data at install time from
the emergency shell? Otherwise I will still have to use Ralf's
instructions, which are a bit more work to follow.

Thanks,
Patrick
