For now, I was planning somehting simple. The catalyst script would just
create a kernel and the ramdisk which would be a simple ext2 filesystem.
The final image would be created by a third-part script like the iso
generation script for the livecd.
Do you absolutely need to not build a kernel or the kernel build will
always be required ?

I'm not familiar with uclibc. If simply copying the uclibc's libc.so
file in the ramdisk instead of the glibc's one works then I can
implement it quickly.
If all apps really needs to be linked against uclibc, I guess it can be
doable too but I'll have to look at it.


I should be able to have somehting running and useable today. I just
finished the kernel generation part. I just need to pack all of the
files. If you want to test, I'm on irc :)
