There is a connotation of temporality associated with the term
"duplicate", in which a "duplicate" would otherwise be considered to
arise "after", not "before", some similar item or event.  This
"duplicate" precedes bug 684280.

Title:
  install "blocked" by unnecessary unmount-partition attempt

Status in “ubiquity” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: ubiquity

  This is specifically with xubuntu-10.04-desktop-i386.iso, booted from
  grub2 with:

  menuentry "Xubuntu Live 10.04 32bit" {
   loopback loop (hd0,2)/xubuntu-10.04-desktop-i386.iso
   linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=/xubuntu-10.04-desktop-i386.iso file=(loop)/preseed/xubuntu.seed --
   initrd (loop)/casper/initrd.lz
  }

  So the xubuntu iso is on the target partition, the partition table is
  NOT to be changed, and the partition has already been formatted.

  Where /var/log/syslog says:

   Step_before = stepReady
   progress_loop()
   umount: /isodevice: device is busy

  then ubiquity is trying to unmount the partition, even though there is
  no need for this.  Even worse, when umount fails, the installation is
  effectively "blocked" from continuing.  That's a "showstopper" bug
  during an install.

  Adding 'exit 0' to the top of /lib/partman/commit.d/01unmount_busy
  allows the install to proceed.

  I assume that some test should be added to 01unmount_busy, so that
  this test is not made when the partition table is unchanged.
