Bootchooser - remaining_attempts

[Çağlar Kilimci]

Hi all,

I am using barebox 2017.03.0 and my bootchooser variables are:
  bootchooser.last_chosen: 2
  bootchooser.retry: true
  bootchooser.system1.boot: system1
  bootchooser.system1.default_attempts: 99
  bootchooser.system1.default_priority: 16
  bootchooser.system1.priority: 20
  bootchooser.system1.remaining_attempts: 5
  bootchooser.system2.boot: system2
  bootchooser.system2.default_attempts: 9
  bootchooser.system2.default_priority: 15
  bootchooser.system2.priority: 10
  bootchooser.system2.remaining_attempts: 3
  bootchooser.targets: system1 system2

And "global.bootchooser.reset_attempts" is empty. I assume counters
will never be reset as written in [1].

So, here is the case that I think it has a problem. system1 has a
problem that does not boot. Bootchooser tries system1 and fails a few
times and then chooses system2. After successful boot of system2,
"bootchooser.system1.remaining_attempts" is still 5. Every boot
sequence bootchooser tries system1 and fails and then system2 is
chosen. If I understand correctly from the documentation, it should be
0 and disabled and will never try at all. Right?

Secondly, There is a bug: if bootchooser.system1.remaining_attempts is
big enough like 10, bootchooser tries to boot system1 as usual and
fails as usual again but it could not boot system2. I am sending the
log below, as a summary "could not open /boot/barebox.env: error 24":
