On a crash, the loopback device also stays mounted and it can't be umounted (not any way that I can find at least)
For example: sudo losetup -a /dev/loop0: [0807]:2613376 (/tmp/vmbuilder_NclQw/disk0.img) -- device-mapper: remove ioctl failed: Device or resource busy https://bugs.launchpad.net/bugs/335472 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
