I want to create a live Linux USB, that would have support for old and new devices (probably having two kernels installed, that you chose on boot, depending on the PC using). I would also like to be able to boot from a Mac.
So basically, I would like to create a boot everywhere live USB. I was using Puppy Linux with a retro kernel, but I would also like to have new features from the new kernel, if the device supports them.
The second problem is when trying to boot from a Mac, since Macs use GPT partition table where older machines use MBR. So I am wondering if this is even remotely possible to achieve? I don't want to carry 3 USB drives with me all the time and I want to use my system everywhere I go :)
The next step, IF this works would be to have the same USB for ARM, Intel...
