Comment 52 for bug 802626

I'm seeing the same issue on Precise, with a non-root LVM disk: a 60-second delay in the boot process, while scripts/init-bottom/udev is waiting for the `udevadm control --exit` process to finish, which is in turn waiting for the `watershed vgscan; vgchange` RUN command.

When run under watershed, the vgchange process hangs forever, waiting for a semop() syscall to return.

If I remove the watershed wrapper from the 85-lvm2 udev rule, then the vgchange process completes sucessfully, and boot returns to normal.
