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?
