[Bug 304259] Re: allow creation of LiveUSB from currently running LiveUSB

[Daniel Richard G.]

I'd like to see this too. It's a bit silly to require an .iso file
matching the running system when the very same files are available under
/cdrom. (Keep the option to install different versions of Ubuntu, of
course, and do require an .iso file then.)

Usb-creator should probably verify MD5 sums in this case, as I've
definitely seen minor file corruption (which can lead to boot failures)
with some flash drives. But for ~700MB of freed-up space, it's worth it.

An old patch by "probono," in a bug report marked as a duplicate of this
one, may be worth a look:

Title:
  allow creation of LiveUSB from currently running LiveUSB

Status in “usb-creator” package in Ubuntu:
  Triaged
Status in “usb-creator” package in Baltix:
  New

Bug description:
  Binary package hint: usb-creator

  It would be nice is USB-Creator could create a LiveUSB image from the
  currently running LiveUSB (as it can from a LiveCD). I believe that
  all required files are available on disk. New persistence file could
  be set to 'none', 'new' or 'clone'.

  This would allow the 'viral' propagation of the Linux distribution in question, and also transfers to newer/larger(?) USB sticks by non-technical people.
