_______________________________________________________
Details:
On Grub 2.02~rc2, when setting the saved_entry variable for example with the
grub-reboot tool, the next boot this variable is read and the matching entry
is booted.
But this is done regardless of the setting of GRUB_DEFAULT, which should
control this setting according to the documentation. It's the same behavior
whether it's set to a specific menuentry or to 0 (as in the example below).
When generating the grub.cfg config file the following code is generated,
which is probably the problematic part:
if [ -s $prefix/grubenv ]; then
load_env
fi
if [ "${next_entry}" ] ; then
set default="${next_entry}"
set next_entry=
save_env next_entry
set boot_once=true
else
set default="0"
fi
