trying to get preseeding on 12.04 64bit with what should be a basic setup to work:

• /dev/sda - the only drive beeing used

• / - rootfs - 100GB

• /boot - 1GB
• /tmp - 10GB
• /data - should take all available space
• swap - 10GB

-

d-i partman-auto/expert_recipe string \
boot-root :: \
1000 50 1000 ext4 \
$primary{ } $bootable{ } \
method{ format } format{ } \
use_filesystem{ } filesystem{ ext4 } \
mountpoint{ /boot } \
. \
500 1000 10000 ext4 \
method{ format } format{ } \
use_filesystem{ } filesystem{ ext4 } \
mountpoint{ /tmp } \
. \
500 5000 100000000 ext4 \
method{ format } format{ } \
use_filesystem{ } filesystem{ ext4 } \
mountpoint{ /data } \
. \
64 2000 10000 linux-swap \
method{ swap } format{ } \
. \
500 3000 100000 ext4 \
method{ format } format{ } \
use_filesystem{ } filesystem{ ext4 } \
mountpoint{ / } \
.

If i only use the code for /boot,swap and / it works. Also i was wondering weather i have to specify some other recipe name than "boot-root", but trying "thisNameIsNotDefinedInPartman" the result was the same.

The Error message displayed by the ubuntu installer is always "no root file system is defined"

Thanks for your help,

Moritz
