last winter I had a build environment, where I could cook packages and cook the kernel, but I did not get out all the different linux packages - all those things like linux-acpi.tazpkg etc. was empty
In Summer, where I had absolute no time, it seemed to work - Arun and Kapil compiled the kernel I am using in my testing iso and Arun wrote a howto http://oldpapyrus.wordpress.com/2013/08/17/quick-guide-to-start-cooking-slitaz-packages/
now it seems to be again broken or I am absolut to stupid - so I opend an extra thread
