[Bug 1745221] [NEW] Default grub config gives warnings

[anatoly techtonik]

Public bug reported:

Grub updates always produce this warning:

Warning: Setting GRUB_TIMEOUT to a non-zero value when
GRUB_HIDDEN_TIMEOUT is set is no longer supported.

And that comes from default grub config file:

$ diff -u3 /etc/default/grub /usr/share/grub/default/grub
$ cat /usr/share/grub/default/grub
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
...
