This has the advantages that it is not likely to appear in any dictionary, it is very mnemonic and if the password is long enough and rich enough in case, it will stand up to a sustained exhaustive search. Around here, quite a few people have .rhosts entries for several machines, often including at least one Sun. Couple this with the fact that, given physical access, anyone can become root on a Sun and you've got widespread vulnerability without the need for any password attack. I do try to be patient, but sometimes it becomes overbearing. No further action is required by you.
