I just checked out the d-i trunk, I'll see what I can do.

It has to be added for all PReP systems which use the mkvmlinuz boot loader,
so that would be all PRePs, if I am not mistaken.

/dev/sda2 isn't the PReP partition. The PReP boot partition *has to be*
the first primary partition on the boot disk. /dev/sda2 is the root
partition of the fresh install in my case and of course this can and
will be different. We only need to know the boot disk, then we know
the place and the name of the PReP partition.

HTH,
Uli
