[Bug 731379] Re: leaves behind /dev/loop[n] devices that can't be removed from unity launcher

[Brian Murray]

These are also visible by looking at the output of 'cat /etc/mtab':

/dev/loop0 /tmp/tmpl1gKA2 iso9660 ro 0 0
/dev/loop1 /tmp/tmpJMBvF6 iso9660 ro 0 0
/dev/loop2 /tmp/tmp9zIPVJ iso9660 ro 0 0

This is still an issue with the Quantal version (0.2.40ubuntu1) of usb-
creator.

Title:
  leaves behind /dev/loop[n] devices and mounted isos

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

Bug description:
  Binary package hint: usb-creator

  I used this to create a couple of USB boot systems. That all went
  fine, but afterwards, for each one, I was left with a loopback device
  visible in the unity launcher and the disk utility. They're not
  mounted, and attempting to mount them fails (showing this in disk
  utility:

  Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/loop0,
         missing codepage or helper program, or other error
         (could this be the IDE device where you in fact use
         ide-scsi so that sr0 or sda or so is needed?)
         In some cases useful info is found in syslog - try
         dmesg | tail  or so
  )

  Looks like some cleanup wasn't done when usb-creator finished (it has
  been closed normally, the loop devices remain). And now there's no
  readily apparent way to make them go away. :-)
