custom partitioning scheme in preseed file for Ubuntu

[praveen bhat]

Hi ,

I am trying to build a Packer based Ubuntu template with custom partitioning scheme as below:

primary partition 1 /boot
Parimary partition 2 swap
Primary partition 3 extended
Extended partition 1 /

I have come up with the below lines in the partitioning section of the preseed.cfg file:

### Partitioning
d-i partman-auto/disk string /dev/sda
d-i partman-auto/method string regular
d-i partman-md/device_remove_md boolean true
d-i partman-lvm/device_remove_lvm boolean true
d-i partman/default_filesystem string ext4
d-i partman-auto/expert_recipe string                         \
      boot-root ::                                            \
              40 50 100 ext4                                  \
                      $primary{ } $bootable{ }                \
                      method{ format } format{ }              \
                      use_filesystem{ } filesystem{ ext4 }    \
                      mountpoint{ /boot }                     \
              .                                               \
              64 512 300% linux-swap                          \
                      method{ swap } format{ }                \
              .                                               \
              500 10000 1000000000 ext4                       \
                      $primary{ } $extended{ }                \
                      method{ format } format{ }              \
                      use_filesystem{ } filesystem{ ext4 }    \
                      mountpoint{ / }                         \
              .
d-i partman/choose_partition select finish
d-i partman/confirm boolean true
d-i partman/confirm_nooverwrite boolean true
d-i partman/confirm_write_new_label boolean true

but the above one is not correct as it is not able to create a root partition.

need help.

This is a general Ubuntu/Debian/preseed question and you will most likely get a faster response if you ask it on serverfault or askubuntu etc.
