+If you are using Galeb with other distributions which are using GRUB, and in
+particular GRUB's os-prober, you might want to add an exception to
+/etc/default/grub so a new menu item for Galeb's partition doesn't get added
+by os-prober every time there is a kernel update. First, take note of the UUID
+of the partition where Galeb is installed:
+
+	# GALEB_PART=/dev/sda2
+	# GALEB_UUID=$(blkid $GALEB_PART |
+	awk 'BEGIN { FS="="; RS=" " }
+	{
+		if ($1=="UUID")
+		{
+			gsub(/["\n]/, "");
+			print $2
+		}
+	}')
+
+then append it to /etc/default/grub in your other distro:
+
+	# cat <<! >> /etc/default/grub
+	GRUB_OS_PROBER_SKIP_LIST=$GALEB_UUID@$GALEB_PART
+	!
+
+You should then regenerate GRUB's configuration file in your distro.
