Being a LiveCD with no persistent storage by default, Tails currently does not use persistent Tor entry guards. In a recent post on the Tor blog, arma discussed the possibility of "improving Tor's anonymity" by increasing entry-guard persistence.
Is it dangerous to use Tails without persistent entry guards? From discussion on the Tails wiki, I gather that there's some tension between making entry guards persistent, and the ideal of complete amnesia. Is there unavoidable tension between being incognito and amnesiac?
