Subject: [PATCH] 00_menu_auto_hide: Reduce number of save_env calls
Normally boot_success will be 1 on every boot (as normally the
previous boot will have been successful). This means that we end
up in the code-path to set boot_indeterminate to 0 every boot.
So we do 2 separate save_env calls each boot, one for boot_indeterminate
and one for boot_success. This results in 2 writes to the disk.
This commit makes us save both boot_success and boot_indeterminate
in a single call, reducing the number of writes, this reducing wear
and tear on the underlying storage.
