[Bug 1548057] Re: rfkill state is not restored on reboot

[Jamie Strandboge]

This still seems to be a problem on Ubuntu 19.04. Ie, if I do:

$ sudo systemctl status systemd-rfkill
● systemd-rfkill.service - Load/Save RF Kill Switch Status
   Loaded: loaded (/lib/systemd/system/systemd-rfkill.service; static; vendor preset:
...

$ rfkill block bluetooth
$ rfkill
ID TYPE      DEVICE      SOFT      HARD
 0 wlan      phy0   unblocked unblocked
 1 bluetooth hci0     blocked unblocked
$ sudo reboot

Then I get:

$ rfkill
ID TYPE      DEVICE      SOFT      HARD
 0 wlan      phy0   unblocked unblocked
 1 bluetooth hci0   unblocked unblocked

and I can see that the state files in /var/lib/systemd/rfkill were not
updated as part of the reboot:

$ cat /var/lib/systemd/rfkill/*bluetooth
0

However, I can workaround this manually by running 'sudo /lib/systemd
/systemd-rfkill' prior to reboot myself:

$ rfkill block bluetooth
$ rfkill
ID TYPE      DEVICE      SOFT      HARD
 0 bluetooth hci0     blocked unblocked
 1 wlan      phy0   unblocked unblocked
$ sudo /lib/systemd/systemd-rfkill
$ cat /var/lib/systemd/rfkill/*bluetooth
1
$ reboot
$ rfkill
ID TYPE      DEVICE      SOFT      HARD
 0 bluetooth hci0     blocked unblocked
 1 wlan      phy0   unblocked unblocked
$ cat /var/lib/systemd/rfkill/*bluetooth
1

In this manner, I can at least have bluetooth in a predictable state.
However, the desirable behavior is likely to have the current state
preserved across reboots. Looking at /lib/systemd/system/systemd-
rfkill.service, it appears all that is missing is an
ExecStop=/lib/systemd/systemd-rfkill....
