Title:
  needless OS probing

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: grub2

  Running "update-grub" takes a very long time as it scans through every
  configured LVM chroot I have:

  There should be a way to either disable os-prober in /etc/grub.d/ or a
  way to blacklist regex device names.
