I have started to read a bit on AdaOS and I have two questions. When it
comes to device drivers how are they going to be implemented. I mean one
of the problems Linux has is that one have to make all the device
drivers onself and somethimes this means reverse engineering. Would one
need to do the same for AdaOS or could on easily port the linux
drivers?

Second:

   Printout Renderer

   This program accepts a data stream in the form of binary 'formatting
   objects', and transforms them into the data to be sent to the printer
   (e.g. PostScript, PCL, or pure TIFF).

   One of the special extra functions of this program is to separately
   accept text for a page header and page footer, which it prints on
   every page. This function is used to ensure that security labels are
   printed.

I don't understand the latter paragraph. Say I want to print a book or
something else from my AdaOS, I wouldn't want extra headers and
footnotes to clutter the page so I guess one can turn this off? But if
on what does it do to security?
