Yes, this does work. However, in this case, the device goes into AP
mode whne the current network disappears and never reconnects to any
configured network if it comes available.

The desired behaviour I would like to have is an AP scan mode which
only selects the AP mode after power-up when the supplicant runs the
first time and no known network is found. If, however, the current
network disappears, the supplicant should scan for this network or any
other known network, but do no switch to AP mode.

For now, I am using sed in an init script which replaces disabled=1
with disabled=0 for the AP network configuration block and re-set it
back to disabled=1 after any of the other networks is found.

Is there any other, maybe cleaner way, to do it?
