[Bug 1771393] [NEW] 18.04 Server "Whole Disk" option does not allow LVM

[Wes Deviers]

Public bug reported:

This is a feature request/WISHLIST item.

It's pretty common (at least here) for us to format VM images with full-
disk ("whole disk") LVM.  Normally we have to drop to a shell and
preconfigure that beforehand so I was super excited to see the new
"Whole Disk" option in the new-style installer.

However, it doesn't have "LVM Physical Partition" as an option.  I'm
genuinely puzzled by this because I would think it's an extremely common
pattern. I must be wrong.

We would really appreciate it if the default installer supported whole-
disk LVM physical partition.  Also, considering how different the
interface is, this might not even be a d-i request any more but it seems
likely.

To clarify, this is the installer equivalent of a 'pvcreate /dev/sdb',
whereas the current workflow only supports a 'pvcreate /dev/sdb1'.
Using full disk LVM PV's makes expansion of disk (either iSCSI, VMDK,
etc) trivial.
