Hello,

I=E2=80=99ve been able to test it on the bare metal as well and I confirm: I
booted the install image a few times and the =E2=80=98wpa-supplicant=E2=80=
=99 service
would be stopped every time, with a dangling =E2=80=98wpa_supplicant=E2=80=
=99 process
running.  Given that this seems to be systematic, I=E2=80=99m not sure my P=
ID
file atomicity hypothesis explains everything.

I=E2=80=99ve tried running:

  pkill wpa_supplicant
  while herd start wpa-supplicant ; do herd stop wpa-supplicant ; done

and that always works (i.e., no =E2=80=9Cfailed to start =E2=80=98wpa-suppl=
icant=E2=80=99=E2=80=9D
error.)

If I run in parallel this:

  while touch /var/run/wpa_supplicant.pid ; do : ; done

then it occasionally =E2=80=9Cfails to start=E2=80=9D, but not very often.

To be continued=E2=80=A6

Ludo=E2=80=99.
