Title:
  The 'new' persistent live method starting in 19.10 no longer works

Status in casper package in Ubuntu:
  Fix Released

Bug description:
  I am iso-testing Focal Fossa and I am creating and maintaining tools
  to create live and persistent live USB drives. Lubuntu Focal daily
  live dated 2020-02-12 works. But the current version of Lubuntu Focal
  dated 2020-02-16 (zsynced approx. one hour ago) does not work when
  using exactly the same method using mkusb-plug, that edits the iso
  file to replace 'quiet splash' with 'persistent  ' /12 characters/ and
  creating an ext partition behind it.

  I noticed that the version of casper has changed from 1.438build1
  (when it worked) to 1.439 so I suspect that this has caused the
  failure.
