[Bug 384973] [NEW] needless OS probing

[Kees Cook]

Public bug reported:

Binary package hint: grub2

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

# update-grub

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