custom configuration

On every BOA upgrade the lshell's configuration file is overwritten (we use to set some custom configs here).

Is there any way to prevent "/var/xdrago/conf/lshell.conf" file to be overwritten as similar as CSF firewall settings using _CUSTOM_CONFIG_CSF variable?

Thanks in advance.

Is there a clean way to add some theme specific editor options (configuration) in a way that neither a Wysiwyg module update nor editor update would overwrite them? For example if you wanted to combine CKEditor with the marinelli theme (see http://drupal.ckeditor.com/tricks), what is the cleanest way to do so (using Wysiwyg module)? I'm inclined to suggest new configuration field for such cases (see http://drupal.org/node/313497), so there would always be at least a dirty way to make such modifications without directly hacking the module/editor.
