[openFATE 310380] grub2 bootonce or bootnext command
Feature changed by: James McDaniel (jdmcdaniel3)

Title: grub2 bootonce or bootnext command

openSUSE-11.4: Unconfirmed
Priority

Description:
<!-- @page { margin: 0.79in } P { margin-bottom: 0.08in } -->
With the possibility of Grub2 being implemented soon as a default boot
manager, it would be useful to add to the Grub2 packaging a small
script that fully emulates the older grubonce that is provided with
openSUSE-11.3 and earlier. 
The philosophy is from run level 3, or from a desktop that does not
support the capability to selectively reboot ONCE (and only ONCE) into
another boot partition, one can run a command that allows this one time
reboot functionality.  This was achieved with the "grubonce" command on
openSUSE-11.3 (and earlier) and other distributions (for the older grub
version) used perl scripts such as bootnext (on Fedora:
http://www.dcheng.members.sonic.net/friends/jspaar/pub/bootnext/ ).
There is an example here on openSUSE forums as to the utility of the
grubonce command and how it can be applied:

The grub2-reboot command is lacking (in comparison to grubonce) in that it
appears it can not be used to generate the re-boot selection
menu.  Hence I propose a small script/application be provided with
openSUSE-11.4 (or 12.0) that functions similar to the scripts proposed
in
http://forums.opensuse.org/english/information-new-users/unreviewed-how-faq/444667-reboot-cli-selective-partitions.html
or as a minium functions with the full capability of the "grubonce"
(which grub2-reboot lacks).

+ With the advent of openSUSE 12.2 and its inclusion of grub 2, this will
+ be a needed option. I have used this in the following bash script for
+ grub legacy:

+ You can set the default boot for the next restart using grub2-set-
+ default, but it does not remove the menu display or change the default
+ timer on restart & you must actually restart your PC. If the default
+ selection time could be made to be zero along with existing ability to
+ select the next default session, this thing might be doable.
+ Thank You,
