[Bug 2107256] Re: Installing over proxmox: ValueError: /dev/pve/data: not an existing file or block device

The issue is that curtin fails to handle LVM thin pools (which are read-
only block devices) that don't show up in the system in
/dev/{vgname}/{lvname} like normal LV-s would.

https://github.com/canonical/curtin/pull/28 should improve things.
