Cleanup the buildtime resolv.conf copied under
/etc/resolvconf/resolv.conf.d by resolvconf-package.
An ltsp plugin to install autopoweroff (but we will not use it,
because it breaks the build, because the autopower-package
is not in Ubuntu repositories).
Install autopoweroff package.
Put autopoweroff configurations (and upstart init-script)
to puppet-rules.
Fix autopoweroff upstart-script.
Change plugin resolution order so that we can override
plugins from here.  Fixes the resolv.conf case.
Run updatedb at a late stage of ltsp image build.
Disable whoopsie (but keep it still installed).
Install libdvdcss2.
Settings for ssh server (actually it's only a placeholder
module for ssh server settings).
Enable acroread.
In case /usr/bin/updatedb is missing, do not abort ltsp image build.
Print an error message (and exit with error), if
ltsp-apply-puppet failed.
Some admin-packages such as mlocate are nice on thin clients as well.
Our lightdm configuration uses backgrounds from liitu-themes.
Install a new (3.6.6-1000-generic) kernel to ltsp image.
Install yet another kernel (3.7.5).
