Specifying mount options to partman-auto

[Paul Chavent <Paul.Chavent@onera.fr>]

Hi

I would like to specify mount options to partman-auto in a preseed conf 
file.

For instance, i have this code

              4000 12000 12000 ext4                           \
                      $primary{ }                             \
                      method{ format } format{ }              \
                      use_filesystem{ } filesystem{ ext4 }    \
                      mountpoint{ / }                         \
                      options/noatime{ noatime }              \
                      options/nodiratime{ nodiratime }        \
                      options/discard{ discard }              \
                      options/async{ async }                  \
                      options/commit{ commit=600 }            \
              .                                               \

It seems that the options aren't taken into account.

My questions are :
 - is there any way to check the parsing of the partman-auto specs 
(like debconf-set-selection -c with the preseed file) ?
 - where is the code that handle options in partman-auto (i have 
searched in partman-{base,partitioning,auto} without success ?
 - is it intended to work this way ?

Thank for your help.

Regards.

Paul.
