I know how stupid this sounds BUT is it possible to install a linux distro that has been loaded to the drive it was booted from?

I was thinking of installing Arch or Puppy to a flashdrive that Would be hosting itself.

OR

Is there a precompiled drag and drop style distro that you can drop the files to and run with constant persistence from drive to drive?

Other limiting factor is that the overall size of distro must be <4GB.

EDIT: To clarify, I want to install a system to a flashdrive that it is livecd'd from. Scenario for reference:

  1. I use LiLi to put ubuntu-minimal.iso on a flashdrive
  2. Boot ubuntu-minimal.iso from flashdrive.
  3. Install the iso to the same drive it booted from.

What do you really mean? I'm running a distro that uses the same drive for /boot and everything else. Is that what you want? – phunehehe Jan 18 at 3:37
@phunehehe - I believe he wants to change all the core system files to a different distro while the system is still running. – jordanm Jan 18 at 3:40

Wouldn't the installation in step (3) destroy the ISO file you put in in step (1)? – phunehehe Jan 18 at 5:09
yes but would it be a viable solution? and would it still be installed? – Cole Busby Jan 18 at 7:30
