tailscale up
tailscale up --auth-key=xxxx

FIX:
tailscale up --advertise-tags=tag:foo
tailscale up --advertise-tags=tag:foo --shields-up=true
tailscale up --advertise-tags= --shields-up=true  # explicitly mentioned good
tailscale up --shields-up=true  # ERROR: unmentioned thing is changing value
tailscale up [--init] --advertise-tags= --shields-up=true  # init is fine

tailscale up
  ERROR: tailscale already running with settings that differ from those not mentioned (sldkjfslkdjf)
         run with --init to

tailscale set --shields-up
tailscale set --shields-up=false

tailscale get
tailscale get shields-up

tailscale set shields-up
tailscale set shields-up=true
tailscale set shields-up=false
tailscale set [--account=NAME] shields-up=false
tailscale set [--account=NAME] alias=home

tailscale set advertise-tags+=tag:foo
tailscale set advertise-tags+=tag:foo

tailscale set shields-up=false advertise-tags+=tag:foo

tailscale down
tailscale up (no args after ==> edit prefs.wantrunning=true, login as necessary)
tailscale up --init (like today: all prefs to implicit flag values)

tailscale up --auth-key=....
tailscale login [--auth-key=] (does not imply --init; use `tailscale set --init`)

tailscale set [--init] shields-up=true

#### Multi-accounts

tailscale account list
tailscale account add [--control-server=http://localhost:123123]
tailscale account remove bradfitz@gmail.com
tailscale account switch bradfitz@gmail.com
tailscale account  bradfitz@gmail.com

tailscale up -a home
tailscale up -a work  # work now ALSO logged in
tailscale down -a work # now just home
tailscale switch home # disable all but home
tailscale switch work # disable all but work

tailscale login # always means force-reauth, used to add a new account
   => same login as now? no change.
   => new login? future => interactive prompt, new account / switch to it
   => new login? now    => reset all settings

tailscale get login


# v1.8 new user docs/flow

## Easy mode:

tailscale up   # login as needed, then bring engine up

## More verbose way:

tailscale login
tailscale set shields-up=true
tailscale up


tailscale logout =>
     - down
     - tell control to drop association (see Direct.TryLogout TODO)
     - does NOT delete prefs (like advertised tags, slksjdlfkj)
