Bug#815934: rfkill state not restored after reboot

[Josua Mayer]

Package: systemd
Version: 215-17+deb8u3
Severity: normal

Dear Maintainers,

I noticed that rfkill state for both wifi and bluetooth is not restored
on reboots on Hummingboard and Cubox-i.

1) Let me focus on wifi first:
The behaviour I see is:
it always starts up soft-blocked no matter if I unblocked it before
rebooting, or not.
In /var/lib/systemd/rfkill a state-file is created which shows 1 if wifi
was blocked before last reboot, and 0 if it was unblocked.

So I conclude that saving the state works fine.
So I investigated the status of systemd-rfkill at rfkill0.service, and
found that its reported to have exited without error.

--> I guess that systemd tries to restore therfkill state too early,
that is before the actual rfkill device / wifi device is properly
initialized. (is this #809323 ?)

There is still a ghost around here, as I got the state restored properly
at least once now, without changing *anything* at all.

2) Bluetooth:
There is no state-file created in /var/lib/systemd/rfkill for the
bluetooth device.
But I should add that this specific bluetooth chip requires manualy
loading firmware from userspace, and only then it comes up.
