For some time i've been trying a few linux distro out there, some realy small, some are so beautiful, some of it is realy challenging to set up and some of it is realy familiar to use.. as in my journey i've look that, there are lots of distro are cooked from ubuntu, for example, Bakctrack 5, Linux Mint Debian Edition, Lubuntu and so on.. and i think this is realy a good, if it has a common characteristic, it will be easy to ask for support.. so i ask myself, can i made a distro based on ubuntu too? where do i need to start? what i need? I come across to every ubuntu forum, thread, and so on, no luck.. then i give up, mybe i should start fresh.. so, i wonder what is the fresh start of ubuntu? what is the base? and what will it size would be? So, i found out that the smallest ubuntu i can start is Ubuntu Mini Remix , which is just 180MB , which u can burn to usb, but it feature only the busybox.. so u need to edit it with some other tool called Ubuntu Customization KIt (UCK) , Customzer, or any other tool that mybe has a same purpose..
