For someone who's in the process of writing his/her own OS,

I would say it's a little confusing (to me anyway) why you would continue to spend time with Linux. Be that as it may, if you prefer to have complete control over which packages get installed during the Slack installation process, there is the "Expert" option which will allow you to individually include or exclude each package. To quote from the Slackware book
http://www.slackware.com/book/ "For the more advanced user, install offers the expert option. This allows you complete control over what packages get installed. You can deselect packages that are absolutely required, resulting in a broken system. On the other hand, you can control exactly what goes onto your system. Simply select the packages from each series that you want installed. This is not recommended for the new user, as it is quite easy to shoot yourself in the foot."
As for recommendations on what packages are essential to install or should be avoided, that would depend entirely on what sort of work you will be doing on your PC. The set of useful packages for a gamer, or a programmer, or a musician, or a business user, etc, etc would all vary. If you specified your intended uses for this machine, I think it would allow others to make recommendations. -- J.W.
