# Note 3: If you use a shell other than zsh things like |&

# Note 7: if you see a strange command check my .zshrc -- it may

(2004dec01)

The idea: from inside my environment (see
<http://angg.twu.net/tourism.html>) I should be able to change between
several "standard" configurations rather quickly -- preferably by
running just a few shell functions or aliases.

# (find-es "tourism")




To do:

* How to reconfigure net parameters -- in a certain place I'll have a
  certain IP/gateway/DNS/mail configuration, in another one I'll have
  other configurations for those, in a third place I'll be on dial-up.

* ntpdate takes about one minute to give up on initialization when the
  system thinks that ethernet is up but it's not responding.

  # (find-fline "/etc/rcS.d" "S51ntpdate")
  # (find-es "init" "update-rc.d")

  cd /etc/rcS.d/; mv -v  S51ntpdate _S51ntpdate
  cd /etc/rcS.d/; mv -v _S51ntpdate  S51ntpdate


* The MTA (exim4) also takes some time when ethernet is up but
  disconnected.

  # (find-available "exim4-daemon-light")
  # (find-status   "exim4-daemon-light")
  # (find-vldifile "exim4-daemon-light.list")
  # (find-udfile   "exim4-daemon-light/")
  # (find-vldifile "exim4-daemon-light.postinst")

  # (find-fline "/etc/rc2.d")


* Reconfiguring X:

  # (find-angg ".zshrc" "prep-X-reconfigure")
  # ^ Not tested.
