Install puavo-wlanap to ltsp image.
Add support for (thin) thin client images for precise as well.
Quantal may be broken right now...
Add openssh-server, when adm_users are created (so that
ssh authorized keys are actually useful).  This is for
thin clients as well.
Remove libnss-extrausers from here, it should come as
a puavo-ltsp-client dependency.
packages::ubuntu is no more (fix quantal build).
Add gcc and gdb for development and especially debugging.
Add iftop and iperf for network analysis.
Disable ondemand CPU frequency scaling (because it triggers
system freezes on some processors).
Remove double definition of "gcc" (should test these first
before committing).
Add a comment clarifying that we do not intend to turn this off
for all machines (in the long run).
Do not try to install some packages we do not have yet
(or never), and remove some we probably do not need
(like extra stuff sitting in gnome-control-center).
Keep some package management enduser applications out.
Move purged packages list to their own class, and purge
packages only after all necessary packages have been installed.
Do not install deja-dup.  Indicator-session is probably okay.
