** Description changed:
+ [SRU Justification]
+ There is a behavior regression on non-EFI systems with the latest SRU of
grub2 which causes unnecessary boot delays.
+
+ [Test case]
+ 1. Install a system using BIOS mode with /boot on LVM.
+ 2. Reboot and verify that the boot menu is shown for 30 seconds at boot.
+ 3. Install grub* from -proposed.
+ 4. Reboot and verify that the boot menu is not shown.
+ 5. Install a system using UEFI mode with /boot on LVM.
+ 6. Reboot and verify that the boot menu is shown for 30 second at boot.
+ 7. Install grub* from -proposed.
+ 8. Reboot and verify that the boot menu is still shown.
+
+ [Regression potential]
+ The test case is sufficient to verify all possible paths work correctly after
the SRU.

KDEneon LTS user edition 5.12, Release 18.04
grub-common 2.02-2ubuntu8.10 from Ubuntu updates
Since latest update near the end of Jan. 2019 (29th?), grub menu has 30
second delay every reboot as though recordfail is set. It did not do
this before the update.
After messing with grubenv and recordfails settings, I found this
paragraph in 00_header in 18.04 that is not in 16.04:
if lsefi; then
- set timeout=30
- if [ x$feature_timeout_style = xy ] ; then
- set timeout_style=menu
- fi
+ set timeout=30
+ if [ x$feature_timeout_style = xy ] ; then
+ set timeout_style=menu
+ fi
fi
Note "timeout=30" which is the same as the recordfail timeout. As a
test, I edited /boot/grub/grub.cfg and changed the 30 to 17 and sure
enough, that's the source of the timeout.
Here's the paragraph from 00_header:
if lsefi; then set timeout=${GRUB_RECORDFAIL_TIMEOUT:-30}
- if [ x\$feature_timeout_style = xy ] ; then
- set timeout_style=menu
- fi
+ if [ x\$feature_timeout_style = xy ] ; then
+ set timeout_style=menu
+ fi
fi
One odd thing is the 00_header file is from Jan 9th but this bug has
just appeared so it must be related to grub-common not the the header
file.
