Public bug reported:
A behavior of grub-pc.config does not allow to reach "replacing config
file with new version", as shown below in a session listing:
# echo grub-pc grub2/linux_cmdline string acpi=force elevator=deadline | debconf-set-selections
# dpkg-reconfigure -f noninteractive grub-pc
Replacing config file /etc/default/grub with new version
Installation finished. No error reported.
Generating grub.cfg ...
...
The problematic code introduced in http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/precise/grub2/precise/revision/31/debian/grub-pc.config (lines 24-38)
(where it overwrites preseeded values in debconf database with call to db_set):
if test -e /etc/default/grub ; then
. /etc/default/grub
db_set grub2/linux_cmdline "$GRUB_CMDLINE_LINUX"
db_set grub2/linux_cmdline_default "$GRUB_CMDLINE_LINUX_DEFAULT"
case grub-pc in
grub-pc)
if [ "${GRUB_TIMEOUT}" != "" ]; then
db_set grub-pc/timeout "$GRUB_TIMEOUT"
fi
if [ "${GRUB_HIDDEN_TIMEOUT}" != "" ]; then
db_set grub-pc/hidden_timeout true
elif egrep -q '^#?[[:space:]]*GRUB_HIDDEN_TIMEOUT=' /etc/default/grub; then
db_set grub-pc/hidden_timeout false
fi
;;
esac
fi
Commenting it out makes the above example in listing to work.
I dont understand the purpose to update debconf preseed values with those from config file.
(assuming db has these already calibrated before adding into db with 'interactive' backend)
