Possible feature Original Submission: As operating systems are becoming extremely stable these days (even in the MS world), the only times I actually reboot my computer are to switch to that /other/ operating system. When I reboot again, it's to get back into my nice Linux environment. While I do have Linux as default, would it ever be possible to have GRUB rotate the default boot between 2 or more partitions? Then, by default, it would boot into a different operating system from what you just restarted in. Is this a feature that other people would like to see? Follow-up Comments ******************* ------------------------------------------------------- Date: 2002-Oct-01 12:07 By: hno I'll second this patch. Much easier than having a forest of grub configuration files like I proposed below, and can be used to solve a number of interesting things including kind of emulation of the lilo -R option as requested in Bug #1241 Regards Henrik ------------------------------------------------------- Date: 2002-Sep-11 16:07 By: hno You should be able to do this with a two stage menu system and using the savedefault option, without any changes to the existing GRUB code Create three grub config files, making up a two levels directory structure -- grub.conf --- default saved hiddenmenu timeout=0 title Alternative 1 configfile (hd0,0)/boot/grub/alt1.conf title Alternative 2 configfile (hd0,0)/boot/grub/alt2.conf --- alt1.conf --- default 2 timeout=10 title Alternative 2 configfile (hd0,0)/boot/grub/alt1.conf title Alternative 1 kernel ... savedefault --- alt2.conf --- default 2 timeout=10 title Alternative 1 kernel ... savedefault title Alternative 2 configfile (hd0,0)/boot/grub/alt2.conf Regards Henrik ------------------------------------------------------- Date: 2002-Jun-16 22:08 By: None --- stage2/builtins.c.ORIG Sun Jun 16 21:10:05 2002 +++ stage2/builtins.c Sun Jun 16 23:50:24 2002 @@ -3197,7 +3197,8 @@ #if !defined(SUPPORT_DISKLESS) && !defined(GRUB_UTIL) char buffer[512]; int *entryno_ptr; - + int entryno = 0; + /* This command is only useful when you boot an entry from the menu interface. */ if (!

It realize the shiva suggestion. ------------------------------------------------------- Date: 2002-Jun-11 00:45 By: shiva I think this could be done by accepting a parameter in savedefault: the name of the boot section to save as the default for the next boot. It would also be nice to have a userland utility that sets the default from a running OS, so you could create desktop shortcuts to boot a different OS next time.
