@Sebastian I use SliTaz 3.0 as my base distro with a dual boot copy of Windows XP for stuff that doesn't work in with Wine.
I'm starting to think SliTaz can't be simply defined like TinyCore could. This is probably why SliTaz looks and feels better than TinyCore to begin with. It aims for simplicity, beauty and small size rather than just simplistic small. Not that I think we couldn't learn something from TinyCore - we could for example create a copy of SliTaz with just OpenBox, PCManFM and a simple panel running with nothing else installed - a lite version from which people can add what they want without having to remove a lot of stuff they don't want.
I also think we need to split up the jobs for SliTaz. People can do multiple jobs, but by splitting them up into groups, we can set up goals for each. I was thinking grouping like documentation writers, packagers, kernel compilers, busybox compilers, bug fixers, graphic designers (for themes, wallpapers, etc) and tool makers. That way we can focus on each specific tasks with set goals we want to achieve. It also means we separate the workload into something each of us can manage with our free time. I think part of the problem with why we failed to release SliTaz 4.0 was because we all tried to do all of these at once or just one at a time. This meant that pankso was stuck doing everything and SliTaz as quickly grown beyond a one-man or few-men project.
I tried using other distro's kernels. It doesn't work all that well for the simple reason that SliTaz wasn't designed for it. This means we have to make our own and use our own packages yet again (it's inescapable it seems).
We also can't be like other distros since nothing comes close. I doubt we'll ever be like Slax or Puppy with a state saved file. I don't really think that's the point since SliTaz isn't mean to be a clone of other distros. I also think we should stick to simple packages, but allow larger more complex packages to exist. Maybe even (*gasp*) some proprietary drivers like those used by Wifi cards. Another thing I was thinking about was the use mode modules and services loaded by default. For example, Puppy comes with usb_modeswitch installed with the cdc_acm and option modules loaded by default. What does this mean? It means I can plugin in my cellphone or 3G Modem and I can connect to the internet using a simple dialer program. It's a small touch and it works wonders when seen. As for the overhead? Probably about 150kb extra for the iso so it might be worth adding ;)
