Bug#563204: (no subject)

[Ralph Ulrich]

I had purged os-prober some time ago but forgotten about. Now I wanted
to reenable os-probing. I saw the file
/etc/grub.d/30_os-prober
despite having purged os-prober (it is a grub-common config file).

1. Now I searched for a package grub-os-prober. Nothing found.
2. Searched for all names grub . Not found os-prober
3. Searched for Version 1.98 . Not found os-prober

After 2 hours examination I got the most easy solution (for dummies):
apt-get install os-prober

I would not have os-prober purged if I knew the entry:
GRUB_DISABLE_OS_PROBER=true in /etc/default/grub
(I wish this for a self explaining commented out entry...)
