You've managed to get a few things working which I'm still struggling with on my own project. (Wolvix) Like getting GDM to work live. (I can't for the life of me get it to launch X while live on Wolvix)
The live installer looks like a great tool. I've not tested it yet, but I really like all the options it provides while it's still clean and simple. The only thing I can put my finger on is that it looks like it's missing an option for having /home on a dedicated partition. Now this might be a design decision, or it might even be there as an option if you proceed with the install. Anyway, great work.
I'm totally jealous of what you've put together here. It's almost as I want to leave my own project behind and start developing for Salix instead...

Good luck with the final release of SalixLive, by the look of RC3 it must be right around the corner.
Cheers!
