[Bug 788298] Re: grub-reboot changes boot default permanently on Lucid LTS
Correct me if I'm wrong, according to [this documentation](https://www.gnu.org/software/grub/manual/grub/html_node/Environment- block.html), on LVM or RAID disk the `/boot/grub/grubenv` file cannot be modified by GRUB, in that case, by the `save_env` routine. Only the OS via `grub-reboot`, `grub-editenv` or `grub-set-default` can modify the `/boot/grub/grubenv` file. Therefore, the `save_env prev_saved_entry` won't work here (on LVM or RAID disk), and the system will not be able to boot on the previously saved entry. Is that correct ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/788298 Title: grub-reboot changes boot default permanently on Lucid LTS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/788298/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 788298] Re: grub-reboot changes boot default permanently on Lucid LTS
** Description changed: - Binary package hint: grub-pc + [Impact] + The grub-reboot manpage says it will "Set the default boot menu entry for GRUB, for the next boot only." But, that's a promise it cannot keep when GRUB cannot write to the environment block, such as when it is stored on Linux software RAID (md) or LVM devices. An administrator of such a system may expect grub-reboot to work as documented, only to find that their change is now permanent, requiring manual recovery. Users without console access may rely on grub-reboot to provide a mechanism for testing a possible-broken boot entry. If that entry causes the system to fail to boot, they may find their system unrecoverable. - This is related to the following bug: - https://bugs.launchpad.net/ubuntu/karmic/+source/grub2/+bug/497326 + [Test Case] + Run grub-reboot on an impacted system and check for a warning and instructions on manually restoring the default. Also, check for a warning in the grub-reboot manpage. - Opening a new bug since the aforementioned bug is related to Karmic. - Although it was marked as "fixed" over 16 months ago, this feature still - appears to be broken in Lucid LTS. - - Ubuntu Release: Ubuntu 10.04.2 LTS - Architecture: x86_64 - Package Version: 1.98-1ubuntu10 - - Steps taken: - - Edited /etc/boot/default and changed "GRUB_DEFAULT=0" to "GRUB_DEFAULT=saved" - - Used grub-reboot so that grub would reboot into Windows on the next boot only - - Rebooted from Ubuntu - - Windows booted as expected - - Rebooted from Windows - - Expected Results: - - After rebooting from Windows, my grub default selection should be back to Ubuntu (or whatever it was before issuing grub-reboot) since grub-reboot is supposed to "set the default boot entry for GRUB, for the next boot only" as per the man page. - - Actual Results: - - Windows remains selected by default at the bootloader screen and boots. Note that this prevents users from being able to reboot into Windows and back when they are accessing their machines remotely. - - Additional Information: - - The system I am experiencing this on is set up as follows: - - Ubuntu is installed on a Linux mdadm raid 1 mirror (/dev/sda1 and /dev/sdb1) - - Windows is installed on an Intel Raid 1 mirror (what would have been /dev/sdc and /dev/sdd are now /dev/mapper/isw_febcbhicb_Windows) - - ProblemType: Bug - DistroRelease: Ubuntu 10.04 - Package: grub-pc 1.98-1ubuntu10 - ProcVersionSignature: Ubuntu 2.6.32-31.61-generic 2.6.32.32+drm33.14 - Uname: Linux 2.6.32-31-generic x86_64 - NonfreeKernelModules: fglrx - Architecture: amd64 - CheckboxSubmission: 60d09ed5715e10eba06ad43865289d68 - CheckboxSystem: f134069bba098730d27f59b402920826 - Date: Wed May 25 15:08:12 2011 - InstallationMedia: Ubuntu 10.04 LTS "Lucid Lynx" - Release amd64 (20100427.1) - ProcEnviron: - PATH=(custom, user) - LANG=en_CA.UTF-8 - SHELL=/bin/bash - SourcePackage: grub2 + [Regression Risk] + This is a documentation change only.

[Bug 788298] Re: grub-reboot changes boot default permanently on Lucid LTS
Regarding the problem of grub-reboot not working with /boot on a RAID array
(and in my case not being able to boot back into Ubuntu), I would be happy with
a timed default. It wouldn't require GRUB_DEFAULT=saved or grubenv. As I
imagine it, a user who normally uses e.g. GRUB_DEFAULT=0 would edit
/etc/default/grub to add something like:
GRUB_TIMED_DEFAULT=6 300 # set the default menu entry to 6 for 300
seconds from when grub.cfg is generated
Then the user would run grub-update and it would result in something
like the following in grub.cfg (using bash command substitution to get
the date but perhaps a special environment variable could be added):
### BEGIN /etc/grub.d/00_header ###
if [ -s $prefix/grubenv ]; then
load_env
fi
set default=0
if [ $(date +%s) -le 1319894091 ] ; then # grub-update at Sat Oct 29 15:09:51
CEST 2011; date is 300 seconds in future
set default=6
fi
if [ ${prev_saved_entry} ]; then
...
If the user reboots at any point in time in the next 300 seconds then
the default menu entry would be 6, after that it would be 0. To guard
against a user forgetting that a timed default setting is present grub-
update could issue an are you sure prompt.

[Bug 788298] Re: grub-reboot changes boot default permanently on Lucid LTS
Jordan Uggla points out that his fourth patch in http://lists.gnu.org/archive/html/grub-devel/2009-12/msg00276.html addresses part of this, by at least making grub-reboot not do anything rather than acting like grub-set-default; I'll think about that patch some more but it seems reasonable. Making grub-reboot raise an error immediately is harder but possible. Actually supporting your configuration for grub-reboot is hard and may not ever happen, as it requires writing to the RAID array and GRUB deliberately doesn't implement that right now due to safety concerns. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/788298 Title: grub-reboot changes boot default permanently on Lucid LTS -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
