I really need some good help on this one! I will put you in the picture first so might be a bit lengthy..
I have a 4GB USB-stick. I want to put about 8 live ISO's each in its own partition. I am trying to use GRUB 2 as a boot manager. I decided that I want to use GParted, SystemrescueCD; PartedMagic; Lubuntu and Mageia. Those last three for i586 and x86_64 archs.
I have been messing around with the distros I mentioned and I am only stuck with Mageia. I should mention that I am trying to avoid FAT partitions. So everything goes in EXTx partitions.
I tried to format Mageia's partition as ext4, then ext2 then FAT32 and still having the same problem
/sysroot has no proper rootfs layout, ignoring and removing offending mount hook
I am pretty sure that I have made the changes necessary to initrd.gz. Grub would load the kernel and initrd.gz until I am left with dracut error above..!
As I mentioned; I tried ext4, ext2 and FAT32 file-systems.
I was googling on the Internet and it seems to have been a known problem. I mentioned in other threads that the LiveCD fails so often on many machines that I try. Different hardware and configurations. But since I was not in a real need for it I dropped it. But now it is different..
Any idea about the reason behind this? Can anybody give me a hint about the ins and outs of dracut? Well; I almost know enough as I was reading through the files of the live initrd.gz,
but an expert help is always appreciated. 
If somone is going to point out UNetBootin and bros., thank you in advance but please refrain! I need the installation of the scenario above. Maybe in the future, on a 32GB USB-stick I'll be able to put the installation DVD's too
