[Bug 1800722] Re: EFI booting + /boot on LVM == inaccessible boot menu
Fixing the spelling on the recordfail timeout changes the timeout on both the
recordfail and efi blocks:
if [ "${recordfail}" = 1 ] ; then
set timeout=0
else
if [ x$feature_timeout_style = xy ] ; then
set timeout_style=hidden
set timeout=0
# Fallback hidden-timeout code in case the timeout_style feature is
# unavailable.
elif sleep --interruptible 0 ; then
set timeout=0
fi
fi
if [ $grub_platform = efi ]; then
set timeout=0
if [ x$feature_timeout_style = xy ] ; then
set timeout_style=menu
fi
fi
This still leaves `GRUB_TIMEOUT_STYLE=hidden`, as the timeout style is
forcefully set to `menu` if running on EFI. The menu indeed does not
show when both the normal and recordfail timeouts are set to 0 (as
expected).

[Bug 1800722] Re: EFI booting + /boot on LVM == inaccessible boot menu
@vorlon When grub-common, grub-efi-amd64, grub-efi-amd64-bin and grub2-common
are installed with version 2.02-2ubuntu8.12 the following configuration options
(in /etc/default/grub) are not honoured:
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
GRUB_RECORDFAIL_TIME=0
The resulting "grub.cfg" has following lines at the end of 00_header-block:
if [ "${recordfail}" = 1 ] ; then
set timeout=30
else
if [ x$feature_timeout_style = xy ] ; then
set timeout_style=hidden
set timeout=0
# Fallback hidden-timeout code in case the timeout_style feature is
# unavailable.
elif sleep --interruptible 0 ; then
set timeout=0
fi
fi
if [ $grub_platform = efi ]; then
set timeout=30
if [ x$feature_timeout_style = xy ] ; then
set timeout_style=menu
fi
fi
These lines override any timeouts or menu styles set in the
configuration (via /etc/default/grub). The result is a 30 second timeout
with a menu when booting grub. Having no recordfail support would
default to 30 second timeout but running on EFI forces the timeout style
to "menu" as well.
When downgrading to version 2.02-2ubuntu8.8 equivalents of the packages
mentioned above, "grub.cfg" has the following output at the end of the
00_header block:
if [ "${recordfail}" = 1 ] ; then
set timeout=30
else
if [ x$feature_timeout_style = xy ] ; then
set timeout_style=hidden
set timeout=0
# Fallback hidden-timeout code in case the timeout_style feature is
# unavailable.
elif sleep --interruptible 0 ; then
set timeout=0
fi
fi
Absent is the "platform == efi" block that forces timeout to 30 seconds
and timeout style to menu. This results in a quiet startup for grub
without any boot delay.
The main issue is 2.02-2ubuntu8.12 (I have not been able to install
2.02-2ubuntu8.10 from the repos directly) overrides GRUB_TIMEOUT_STYLE and
GRUB_TIMEOUT without any warning. This means that GRUB_HIDDEN_TIMEOUT and
GRUB_HIDDEN_TIMEOUT_QUIET are also never used. The previous behaviour is as
described above, where the quiet boot happens without boot delay.
I indeed have /boot on LVM on an EFI system but what I want from grub is
quiet boot with no timeout, which the 2.02-2ubuntu8.8 version provides.
I feel this is a regression due to how earlier behaviour is no longer
happening as expected nor are there any warnings about this when running
update-grub. Running on EFI and LVM is not an excuse to silently ignore
configured defaults. There should at least be a warning that the
configured defaults are going to be ignored.
I have not tried to see if you only need to downgrabe grub-common or
grub2-common for the old behaviour to return.

Hello Steve, or anyone else affected, Accepted grub2 into cosmic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/grub2/2.02+dfsg1-5ubuntu8.1 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-cosmic to verification-done-cosmic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-cosmic. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Changed in: grub2 (Ubuntu Cosmic) Status: New => Fix Committed ** Tags added: verification-needed verification-needed-cosmic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1800722 Title: EFI booting + /boot on LVM == inaccessible boot menu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1800722/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1800722] Re: EFI booting + /boot on LVM == inaccessible boot menu
** Description changed:
+ [Impact]
+ This issue makes it impossible for UEFI users to access to boot menu and
choose their kernel if /boot is installed on LVM.
+
+ [Test case]
+ 1) Install Ubuntu on UEFI; put /boot on a LVM LV.
+ 2) Reboot after the install
+ 3) Verify that you will get a GRUB menu at boot.
+
+ [Regression potential]
+ Give particular attention to boot behavior on different disk setups: failure
to show the menu on LVM or other disk setups when holding the SHIFT key, or
showing the menu at every boot unnecessarily on other types of disk
configurations: /boot on a physical partition, etc.
+
+ ---
+
Because EFI does not support instantaneous read of modifier keys (i.e.
holding down shift at boot), the only way to reliably show a boot menu
is by letting the system boot, interrupting the boot, and letting the
menu be displayed because 'recordfail' has been set.
If /boot/grub is on LVM, recordfail does not work, because grub doesn't
have write support on LVM, so saveenv doesn't work. Indeed, from the
grub.cfg on such a system, the recordfail function is written as:
function recordfail {
- set recordfail=1
- # GRUB lacks write support for lvm, so recordfail support is disabled.
+ set recordfail=1
+ # GRUB lacks write support for lvm, so recordfail support is disabled.
}
The interaction of these two limitations means that systems with
/boot/grub on LVM cannot reliably get a grub menu, ever.
While I think that in the long term we should always put /boot/grub on
the ESP (which means it will always be writable by grub), which is in
fact what we did for Ubuntu Core, in the meantime I believe what we need
to do here is always show the boot menu if we are booted under EFI and
we have a non-writable grubenv.
