Bug#472595: update

[Sam Powers <sam@rm-r.net>]

I just tested the install process again by modifying iso-scan.postinst by 
hand, switching disk for partition in the DEVS= statement and found that 
it worked quite well to allow the installation to proceed smoothly.

Again, this made it work for me, but YMMV.
