Title:
  Ubiquity: Manual partitioning: Add "physical volume for LVM", and make
  it possible to encrypt it

Status in ubiquity package in Ubuntu:
  New

Bug description:
  The default volume group (VG) name in both Ubuntu, and Ubuntu Server
  is: ubuntu-vg

  ###########################
  Boot issue
  * You cannot boot an Ubuntu (or Ubuntu Server) disk drive, if you have another disk drive attached with Ubuntu (or Ubuntu Server) installed.

  ###########################
  Disk mount issue in other distros

  * In other distros that are usign other VG names: If you attach other
  disk drives that have identical VG names, they will not be mounted.
  And only one disk drive will be mounted if you are trying to mount
  them:

  $ sudo apt-get install lvm2
  $ reboot

  Then:
  $ sudo modprobe dm-mod
  $ sudo vgchange -a y
    WARNING: VG name ubuntu-vg is used by VGs HW3PiJ-YN4Z-YlBb-IQin-CE00-1xnq-YKwsbc and 2afQMx-nuzj-xw8I-dEkY-n969-jM5v-zn1MSg.
    Fix duplicate VG names with vgrename uuid, a device filter, or system IDs.
    WARNING: activating multiple VGs with the same name is dangerous and may fail.
    1 logical volume(s) in volume group "ubuntu-vg" now active
    WARNING: activating multiple VGs with the same name is dangerous and may fail.
    device-mapper: create ioctl on ubuntu--vg-ubuntu--lv LVM-2afQMxnuzjxw8IdEkYn969jM5vzn1MSgnfgWV7d1tEfHHYXR33JuS7XxqMRcPgiB failed: Device or resource busy
    0 logical volume(s) in volume group "ubuntu-vg" now active

  #########################
  Solution

  For "Manual partitioning":
  * Like in "Erase disk and install Ubuntu" option: 1) Add "physical volume for LVM" 2) Make it possible to encrypt it
  * Add a default VG name, but make it possible to change it to avoid the issues described in the top of this issue.
