  11 #     - listed in 'bos listusers fritz'
  12 #  - and who has been set up with Domtool admin privileges by:
  13 #     - running 'domtool-adduser $USER' while holding AFS admin tokens as
  14 #       someone who is already a Domtool admin
  15 #     - running 'domtool-admin grant $USER priv all' as someone who is already a
  16 #       Domtool admin
  17 #       (To bootstrap yourself into admindom:
  18 #         1. Run '/etc/init.d/domtool-server stop' on deleuze.
  19 #         2. Run '/etc/init.d/domtool-slave stop' on all Domtool slave machines
  20 #            (e.g., mire).
  21 #         3. Edit ~domtool/acl, following the example of adamc_admin to grant
  22 #             yourself 'priv all'.
