Could you set arc.enabled and arc.terms.accepted preference, too?

[xiyuan, 2016/11/16 19:00:17]

If we need to do this, we need to do it somewhere else, probably in
UserSessionManager::FinalizePrepareProfile. This is because the
ArcKioskAppLoggedIn and friends are called after cryptohome auth but before user
profile is finished loading. Thus PrefService is not available here.

[Sergey Poromov, 2016/11/17 12:33:13]

Both of these preferences are set fir ARC kiosk in
ArcAuthService::OnOptInPreferenceChanged()
