if you want to test your partman receipts. here is a tiny guide on how you can get presseded automatic partitioing to work
put the following as a textfile called myseed on a floppydisk
d-i partman-auto/disk string /dev/discs/disc0/disc d-i partman-auto/expert_recipe_file string /lib/partman/recipes-debian-edu/12-boot-root d-i partman/confirm_write_new_label boolean true d-i partman/choose_partition select Finish partitioning and write changes to disk d-i partman/confirm boolean true
note: all lines start with d-i, and are rather long.
on the cd boot prompt type
the installer will now run and automaticaly configure according to your recipe file /lib/partman/recipes-debian-edu/12-boot-root
while writing your recipe you might want to put it on the floppy too and use
d-i partman-auto/expert_recipe_file string /floppy/myrecipe
this saves you from waiting on a new etch test for testing your recipe.
