    expects from authorized_keys: we don't want monkeysphere to be a
    weak link in the filesystem.
 
+What happens when there are no entries in the authorized_user_ids file
+   for a user?  /var/cache/monkeysphere/authorized_keys/$USER.tmp
+   seems like it gets created and then left there.
+
+What happens when a user account has no corresponding
+   /etc/monkeysphere/authorized_user_ids/$USER file?  What gets placed
+   in /var/cache/monkeysphere/authorized_keys/$USER?  It looks
+   currently untouched, which could mean bad things for such a user.
+
+Consider the default permissions for
+   /var/cache/monkeysphere/authorized_keys/* (and indeed the whole
+   directory path leading up to that)
+
+What should happen when an admin does 
+   "monkeysphere-server update-users not_an_existent_user"?
+   currently, it adds
+   /etc/monkeysphere/authorized_user_ids/not_an_existent_user, which
+   seems rather wrong.
+
+is /var/cache/monkeysphere/authorized_keys/$USER.tmp guaranteed to
+   avoid collisions?  Why not use a real mktemp file?
+
+As an administrator, how do i reverse the effect of a
+   "monkeysphere-server trust-keys" that i later decide i should not
+   have run?
+
 Make sure alternate ports are handled for known_hosts.

 setting up authorized_user_id configuration on george was also more
 cumbersome than it needs to be.  Here's what i (dkg) did:
 
- GNUPGHOME=/etc/monkeysphere/gnupg gpg --keyserver subkeys.pgp.net --search dkg@fifthhorseman.net
- GNUPGHOME=/etc/monkeysphere/gnupg gpg --fingerprint dkg@fifthhorseman.net
-
-set up the authorized_user_ids (why are these in /etc/ and not in
-people's home directories?)

+then i added a scheduled:
+
+  monkeysphere-server update-users
+
+to run hourly via /etc/crontab
+
+and made sure that root's keys were working with a temporary symlink
+(see TODO about that business)
+
+and then modified /etc/ssh/sshd_config with:
+
+ AuthorizedKeysFile      /var/cache/monkeysphere/authorized_keys/%u
+
+
+Some outstanding questions:
+
+ * why are the authorized_user_ids stored in /etc/ and not in people's
+   home directories?
+
+ * why are authorized_user_ids managed with a special sub-command of
+   monkeysphere-server, instead of just being hand-managed files, the
+   way that authorized_keys are in stock openssh?
+
+ * Should we ship a scheduled monkeysphere-server update-users cron
+   job automatically?
+
+ * why was i not prompted to confirm the trust-keys line, which seems
+   like the most delicate/sensitive line of all of them?
