[pve-devel] [PATCH installer v2 0/6] auto-installer: add option for providing hashed root password

[Christoph Heiss]

This series adds a new answer option `global.root_password_hashed`
for the auto-installer, enabling administrators to specify the root
password of the new installation in a hashed format - as generated by
e.g. mkpasswd(1) - instead of plain-text.

Administrators/users might want to avoid passing along a plain-text
password with the different answer-fetching methods supported by the
auto-installer, for obvious reasons.

While this of course does not provide full security, sending a hashed
password might still be preferred by administrators over plain text.

Tested by installing using the GUI and TUI (to ensure no regressions
can happen) and using the auto-installer, once with `root_password` set
(again testing for potential regressions) and once with
`global.root_password_hashed` set instead, testing the new
functionality.

First two patches are small cleanups and may be applied independently.

v1: https://lists.proxmox.com/pipermail/pve-devel/2024-May/063949.html

Notable changes v1 -> v2:
  * rebased on latest master
  * fixed rebase mistake
  * merged previous patch #4/#5 for consistency across crates
  * improved validation in auto-installer

Christoph Heiss (6):
  common: move `PasswordOptions` type to tui crate
  tui-installer: remove `Debug` implementation for password options
  low-level: change root password option to contain either plaintext or
    hash
  {auto,tui}-installer: adapt to new `root_password` plain/hashed setup
    option
  auto-installer: add new `global.root_password_hashed` answer option
  auto-installer: add test for hashed root password option
