5 # - as a user with an /etc/sudoers line
6 # - member of "wheel" unix group on deleuze
7 # - while holding tickets for a user who can 'ssh -K' to mire
8 # - and is a member of "wheel" on mire
9 # - while holding tokens for a user who is:
10 # - a member of system:administrator
11 # - listed in 'bos listusers deleuze'
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'.
23 # 4. Run '/etc/init.d/domtool-server start' on deleuze.
24 # 5. Run '/etc/init.d/domtool-slave start' on all Domtool slave
25 # machines.
26 # 6. Run 'domtool-adduser' as above.)
