5# - as a user with an /etc/sudoers line
64f69c08 6# - member of "wheel" unix group on deleuze
78725790 7# - while holding tickets for a user who can 'ssh -K' to mire
64f69c08 8# - and is a member of "wheel" on mire
d2462e94 9# - while holding tokens for a user who is:
10# - a member of system:administrator
11# - listed in 'bos listusers deleuze'
241a0263 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.)
