[pve-devel] [PATCH installer v6 22/36] auto-installer: helper: add subcommand to view indentifiers

[Aaron Lauterer <a.lauterer@proxmox.com>]

It will collect the information from the current system and show the
payload of identifiers that will be send.

To avoid confusion, the subcommands for the device info and filter
matching have been renamed.
