=================== BUG #785: LATEST MODIFICATIONS ================== http://savannah.gnu.org/bugs/?func=detailbug&bug_id=785&group_id=68
Changes by: Anonymous user Date: Tue 08/12/2003 at 18:25 ------------------ Additional Follow-up Comments ---------------------------- An external tool wont be able to reset the default entry number, if the kernel panics. For remote booting of new kernels, there needs to be a 'one-shot' option, or better yet it detects a boot-loop, say more than 3 in 5 minutes and boots a fail-back image. =================== BUG #785: FULL BUG SNAPSHOT =================== Submitted by: jayberkenbilt Project: GNU GRUB Submitted on: Mon 07/01/2002 at 11:17 Category: Configuration Severity: Major Priority: None Bug Group: Feature Request Resolution: None Assigned to: None Status: Open Release: 0.91 Reproducibility: None Planned Release: Summary: would like to change default for only next boot from running system Original Submission: I have a grub menu with several items on it. I almost always choose the same one. Occasionally, I want to boot from a different item on the next boot, but then want to return to by default for subsequent boots. I would like to be able to override the menu item that will appear as the default on the next boot only and to be able to do this from my running system before rebooting. This is different from using savedefault. For example, once in a while, I boot into Windows instead of Linux. I have a menu item called "dark" that does this. I want to be able to run bootdark from Linux and have the system boot into windows the next time I boot. Then, the time after that, I want it to go back to Linux again. You could do this with lilo by using lilo -R. Right now, I'm acheiving this goal by having a bunch of different grub configuration files that do various setups and installs, and I have a script that changes which grub configuration file is in use, but this is not clean. It seems to me that savedefault must be writing something like this somewhere -- perhaps at the beginning of stage2 -- and that it wouldn't be a hard software change to support this request in a similar fashion. The main reason for doing this is to be able to control booting remotely in a safe way. I want to be able to control my next boot without having to be physically present at the machine. For example, I can boot once into Windows, and then reboot from there using VNC. I can't run grub from Linux, so the only way to get back once I've done that (short of messing with active partitions, etc.) is to have the default switch back upon the next boot. Thanks for your consideration.

Anyway, the last comment was made by the original poster.... ------------------------------------------------------- Date: Mon 09/16/2002 at 11:42 By: None Changing the default entry would be one step, but in order for my suggestion to work, it would have to be changed in such a way that the default would revert back for the next time, even if the system is booted into an operating system from which GRUB can't be configured. It would be sufficient to, in addition to being able to override the next default, to be able to set the default for the next boot in the grub configuration file. (Right now, the only thing you can do is "safedefault".) If I could, for example, say that my next boot it is default to the third entry and to set in my grub configuration item for the third entry that it should restore the default to the first entry, that would do the trick. ------------------------------------------------------- Date: Wed 09/11/2002 at 12:18 By: hno Writing a tool that changes the default entry should not be too hard.. The location where the saved default entry number is located is documented in the "Internals" section in the GRUB manual.
