It is independent of the type of underlying devices.

The problem is that with incremental array assembly, when not all
devices are present, we need some timer, and have to run the array
with whatever number of devices available as we currently have.

This is something I overlooked when switching from one-time array
assembly to incremental mode.  Incremental mode is needed when
the underlying devices are slow, there were multiple bugreports
about debian mdadm which can't assemble raid arrays on devices
such as mpt or usb.

Current initramfs-tools infrastructure does not have necessary
infrastructure for such a timeout.

But more important, personally I can't work with any package
which touches debian-installer, because apparently some of the
more important d-i team members dislikes me.  So I can't really
fix anything in mdadm anymore, as it produces d-i component.

Thanks,
