Info: I'm using SliTaz 4.0, on a one year old Samsumg Notebook with an Intel Dual Core i-3 processor, from the LiveCD.
First of all let me start by saying I think StliTaz is a very promising system and well designed in many aspects I've seen (it has great functionality and a simple layout) which is why I chose to use it. But, calling SliTaz 4.0 a "stable" version is very dishonest... it looks like its still cooking to me.
If you want people to use your system, the first priority should be getting people past the first boot screen quickly and easily. This means ironing out all the boot bugs, AND making sure the CreateUSB or LiveCD functions work normally. Both are not true.
The CreateUSB function created a USB and copied all the files, but put them in the wrong directory. That could be found and fixed in the most basic test of the program (does my CreateUSB program make a functional USB?). You folks seem plenty smart and I assume have tested the features, then how could something like this happen?
Secondly, to boot up in generally is tragically buggy, I have to specify the language pack first, because trying to boot without the language back configured first will stall the program before loading the desktop (so essentially no desktop and half a working OS).
With so many bugs on start up, it is only appropriate to call SliTaz 4.0 "still cooking".
I recommend re-releasing 4.0 and thoroughly going through all the main boot options manually to work out the strange little bugs that exist there. Again, getting in the door, that initial boot up, is hugely important, it must take a higher priority in coding.
As an example, look at the Tor browser. It is so good it doesn't even need an install, and works right out of the extracted files, with Mozilla, HTTPSeverything, ect, all right there and working in no time. People trying a product like that are going to be using in long into the future.
ps (I know you folks do this for free, but you do make your product for other people, and I assume you want people to use it. So don't crap all over me for giving you some criticism)
