When I started building my first cab, I was experimenting with Linux... It was all new to me, and I was using Mandrake 9 (which was also new) at the time. Had there been more support, I probably would have pushed a little further to learn, but as it was, all the good front ends were for Windows and it was one more hurdle in the way of completing my project.
I say if you have a Linux front end, by all means get the info out there. I'd be willing to try again. I've been checking in on the other Linux stuff from time to time.
