I was close to creating a post in https://xcp-ng.org/forum/ before stumbling on xcp-ng/host-installer#18 (comment) - I suppose it is desirable to avoid posts where possible :)

Actually, supplying a password should work whatever the type, from what I read in the code: https://github.com/xapi-project/xsconsole/blob/75a5162eb7fb2a97edc83ab6b2dd0a7abcfa274f/plugins-base/XSFeatureEULA.py#L95

Suggested change

	Supplying a password of type="hash" will suppress the EULA prompt on first boot.
	If no password is supplied in the answerfile, users will be asked to accept the EULA and then set the password at first boot.
