I would like to install Ubuntu on a flash drive with the following specifications:
I want to
- be able to make updates,
- be able to install my own software,
- have a persistent partition for my data,
- have the same hardware detection like the live USB versions,
- be able to boot EFI and legacy modus.
Does anybody know how to do that? The only thing I know right now is Knoppix when I install it on my USB stick. But Knoppix is full of software that I don't know and security wise I am not so convinced.
Thank you in advance
