I had thought of trying packaging. I've read that you need a lightweight system to do it so would I need to use a Light edition of VL? I thought I also read that you could use Standard edition but I would like to confirm that.
Whether you use Light or Standard, you have to keep it clean. This means no proprietary drivers, no added programs, just a stock system with nothing added but patches from the patches repo. As you can imagine, this is probably not what you'd want for your everyday use.
I had an unused 4-gig partition on one computer. I installed VL6 Light on it solely for packaging purposes (I'm just getting started). I've made a backup of that partition on an external hard drive so I can simply wipe the VL6 Light installation and restore it "clean" from my backup after I create a package.
I find it frustrating to be unable to add anything to my VL6 Light partition, but it's necessary if I want to keep it clean.
