[pve-devel] [PATCH installer v2 5/6] auto-installer: add new `global.root_password_hashed` answer option

[Christoph Heiss]

This allows user to specify the root password in a hashed format,
generated using e.g. mkpasswd(1), instead of plaintext.

Changes v1 -> v2:
  * move root password setting validation into own function
  * explicitly check for case for both are unset
