[pkg-wpa-devel] Bug#756847: wpasupplicant: systemd wpa_supplicant.service wrong behavior on target isolate

[debianizzato]

Package: wpasupplicant
Version: 1.1-1
Severity: normal

Dear Maintainer,
I switched from sysvinit to systemd in Debian Jessie.
I created a personalized systemd target similar to graphical.target, just adding some Conflicts directives in order to stop some daemons (mysql and apache2).
When I switch from graphical.target to personalized.target and vice-versa (using systemctl isolate <name>.target), everything works fine, except that WiFi connection in Gnome3  Network Manager drops and then restart.
Syslog reports that it is wpa_supplicant.service that stops and then restarts.

I think that it is not a desiderable behaviour of wpa_supplicant.service, unless it is explicitly stopped by a target.

I tried to edit wpa_supplicant.service configuration:
1) I created a wpa_supplicant.service.d directory in /etc/systemd/system
2) I edited a personalized.conf file in it, in which I added the following 2 lines:
    [Unit]
    IgnoreOnIsolate=true
3) Then I restarted daemons and reloaded wpa_supplicant.service
4) systemd-delta reports that wpa_supplicant.service has been EXTENDED
5) switching from graphical.target to my personalize.target works fine, Wifi connection is not stopped.
6) errors happens when I switch to rescue.target and then back to graphical or personalized targets:
    - rescue shell is not closed
    - gnome3 doesn't load properly (just shows desktop image, but no login window)
    - I need to force a reboot
    - I suspect that it is an issue related to DBus (I am not an expert.....)

Do you think it is possible to fix wpa_supplicant.service ?
thanks
