So, tried again.
The param in /etc/default/macchanger is set to "=true"
--------------------
# before bringing up any network interface, run macchanger. Careful, this is
# not guaranteed to prevent leaking your real MAC address before the new one
# gets assigned!
#
ENABLE_ON_POST_UP_DOWN=true
# by default, macchanger runs on all network interfaces but loopback (lo). If
# you only want it to run on specific network interfaces, set them here:
#
#ENABLE_INTERFACES="wlan0"
--------------------
Hoqwever, it looks, somewhere the IFACE variable is wrong set. But it looks
like, this is not set
by macchanger.
I searched through all configs below /etc, but could not find any.
This is the log output of macchanger:
--------------------
IFACE = --all
/usr/bin/macchanger: unrecognized option '--all'

Report bugs to https://github.com/alobbs/macchanger/issues
IFACE = lo
ignoring loopback
--------------------
Hope this helps.
