casper toram doesn't free /dev/loop0 after copy
Status in “casper” package in Ubuntu:
When booting Ubuntu 12.04 livecd using the "toram" option to copy the
CD image into RAM before proceeding, casper mounts the imstallation
media at /isodevice at boot. This device is no longer necessary once
the image copy is complete, and therefore unmounting it should work if
requested by the user.
However, attempting to umount it fails claiming it is busy, yet fuser
-m provides nothing. It turns out that /dev/loop0 is still bound to
the image stored on /isodevice.
I agree it's perfectly reasonable to keep /isodevice mounted after
boot toram in case the user wants something on there, but it should be
easy via gui or cli to umount it, and since the loopback doesn't show
in lsof or fuser -m, many intermediate users are going to be stumped
Since yanking the device anyway doesn't cause any problems, I would
consider this a minor bug concerned primarily with user friendliness.
