[Bug 125702] Re: casper-rw fs not cleanly unmounted on persistent live USB shutdown

[Ben Greear]

Well, I think I finally have this working...mainly due to lots of help from the aufs maintainer and mailing
list.

Will attach the /etc/init.d/umountrootfs and casper initrd scripts (for Ubuntu 12.04).
You have to re-spin the live-cd initrd to get the casper changes in place.  The
umountrootfs just needs to be copied to /etc/init.d/umountrootfs (on the live-cd
image you are re-spining).

** Attachment added: "Make /cow visible, add fsck for casper-rw."
