Comment 2 for bug 1539934

I found a temporary solution that seems ok for now. This article walks through the addition of an initramfs hook to add the necessary kernel modules and and executables to the initramfs image so that the boot process can deal with lvm thinpools and thinvolumes.

http://askubuntu.com/questions/673815/how-do-i-start-my-laptop-with-root-partition-on-lvm2-thin-pool

To recap, create file /etc/initramfs-tools/hooks/thin-provisioning-tools:

#!/bin/sh

PREREQ="lvm2"

prereqs()
{
        echo ""
}

case $1 in
prereqs)
        prereqs
        exit 0
        ;;
esac

. /usr/share/initramfs-tools/hook-functions

copy_exec /usr/sbin/thin_check
copy_exec /usr/sbin/thin_dump
copy_exec /usr/sbin/thin_repair
copy_exec /usr/sbin/thin_restore
copy_exec /sbin/dmeventd

manual_add_modules dm_thin_pool

Then update the initramfs image:
# chmod 755 /etc/initramfs-tools/hooks/thin-provisioning-tools
# update-initramfs-tools -u

After reboot, things work as expected. I expect the thin-provisioning-tools package should be updated to make these changes. What is the right way to report this as an issue with this package?
