Bug#896826: partman-auto: Wrong minimal disk size calculation when using expert_recipe and lvm partitions
Package: partman-auto
Version: partman-auto
Severity: important
Tags: d-i
Dear Maintainer,
* What led up to the situation?
Trying to pressed the debian installer for automatic partitionning.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Used these preseed rules:

* What was the outcome of this action?
Partitionning fails with the following message in syslog:
"partman-auto: Available disk space (2147) too small for expert recipe(3994);
skipping"
* What outcome did you expect instead?
Partitionning successfull, with LVM setup correctly.
The computed size should be /boot + swap + VG(system) = 2074, which would fit
on
the disk (2147).
I believe the problem to be in lib/recipes.sh, function min_size, which adds
the
min_size of _all_ partitions, including those that are LV setup to be part of a
VG.
As a result, the computed min_size is larger than what it would actually be.
I'm sorry i can't work on a patch, since it is more complicated that just
ignoring partitions using $lvmok{ }, and i don't have time right now.
The function should also check that all the LVs can fit in their designated VG,
which may not be defined in the recipe (default one, or created by another mean
before partman-auto)
