Bug#653305: partman-auto: Please provide hook when disk is too small for the expert recipe

[Petter Reinholdtsen <pere@hungry.com>]

Package: partman-auto
Version: 96
Severity: important
Tags: patch
User: debian-edu@lists.debian.org
Usertags: debian-edu

When installing a Debian Edu
main-server+workstation+thin-client-server on a virtual machine with
20 GB virtual disk, the partitioning recipe specified by Debian Edu is
silently ignored and the wrong partitioning setup is used (only one
partition for /).

We would like to be able to detect this in Debian Edu, and ask the
user how to continue, but the partman-auto code lack any hooks to
allow us to do this.

A hook like this might solve it.  Please include in a future version
of partman-auto.  Is this acceptable for Squeeze?
