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 e2fsck for casper-rw." https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/125702/+attachment/3151350/+files/casper -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/125702 Title: casper-rw fs not cleanly unmounted on persistent live USB shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/casper/+bug/125702/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
