partman-auto-lvm patches requiring LVM2?

[Colin Watson <cjwatson@debian.org>]

Hi,

Fabio Massimo di Nitto did a bunch of work on partman-auto-lvm in Ubuntu
(http://people.ubuntu.com/~fabbione/pal/) to make it work more smoothly
and perhaps be usable as a default partitioning method; I'd like to get
these changes back to mainline d-i (and I committed a few of the simple
and obvious ones this afternoon).

However, some of the changes require LVM2. Are we in a position where we
can just say that if you want to use partman-auto-lvm then you have to
use LVM2, or do we still have to maintain LVM1 compatibility?

    - brownpaper bag.. it's ok to switch to kbytes.. but not everything can
      handle so big numbers.

partman-auto-lvm (2ubuntu2) breezy; urgency=low

  * Fabio M. Di Nitto
    - Try to give more sensible names to partitions that are not mounted.
    - Add db_progress info to perform_recipe_by_lvm.
    - Fix partition size calculation using kbytes instead of Mbytes.
      This operation removes any weird hack in calculating the partitions.

    - Ubuntu branding for the master template file.
    - Add 40 some_device_lvm based on partman-auto counterpart.
    NOTE: all the next changes will make partman-auto-lvm useful only with
    lvm2 and the lvm_tools.sh API rename is done to keep a bit of consistency
    with what real lvm2 tools actually do.
    - Use vgs to simplify VG_list (lvm_tools.sh).
    - Rename new_VG to VG_create (name more similare to vgcreate).
    - Avoid useless loop in VG_create.
    - Use pvs to simplify VG_of_PV.
    - Rename detach_PV to VG_reduce.
    - Simplify VG_reduce.
    - Rename attach_PV to VG_extend.
    - Rename new_LV to LV_create.
    - Implement the "full" option in LV_create.
    - Rename delete_LV to LV_remove.
    - Cleanup LV_list.
    NOTE: the following change requires partman-auto-41ubuntu3 or higher.
    - Use expand_scheme and clean_method from recipe.sh to remove duplicate
      code.
    - expand_scheme needs a valid free_size value to return a proper $scheme
      back. Also note the size hack in perform_recipe_by_lvm due to lvm
      rounding issues. In order to fill up the space, the last partition will
      be created using all the free_size and a 3% of the overall space is
      reserved to ensure that the last partition is big enough.
      There might be better methods to calculate, but right now this one seems
      to fullfil its task.
    - Flush udev queue in vg_all_free/do_option otherwise the devices might
      not be there yet.
    - Map devfs names to real devices in vg_all_free/do_option since lvm2
      tools don't like devfs names.
    - Create a separate /boot and a vg on the selected device.
    - Allign vg creation between vg_all_free and some_device_lvm.
    - Add notes on scheme manipulation.
    - Remove wrong call to clean_method in perform_recipe_by_lvm.
    - Fix device mapper naming.
    - Restart partman at the end of the process. This is required to get some
      LVM info right.
    - Add missing noheadings to LV_create.
    - Strip the decimal in LV_create.
