Sorry for not being clear, it's early over here. My point was:<br>
<br>
Unmounting the SD card should be a separate process, usable without
doing a complete shutdown.<br>
<br>
Regarding a fixed delay, I would rather proceed to the actual
unmount as soon as the "unmounting" event has been processed by all
listeners, i.e. on the event's done callback. Unmounting listeners
just need to close their files, no need to introduce delays there.<br>

That is why I was thinking of two signals:
<div class=""><br class="">
</div>
<div class="">
<ol class="MailOutline">
<li class="">“ShuttingDown”. This would be sent when the
shutdown process was initiated. My suggestion is to then
delay 20 seconds (to give peripherals time to cleanly
shutdown) before proceeding to the next stage. The signal is
intended to ask peripherals and systems to cleanly prepare
for shutdown.<br class="">
<br class="">
</li>
<li class="">“ShutDown”. This would be sent 5 seconds before
the actual shutdown. The signal is intended to ask
peripherals and systems to prepare for shutdown now.</li>
</ol>

Writing the code last night, it seemed that the
shutting down of wifi/simcom/etc was messy.
<div class=""><br class="">
</div>
<div class="">Perhaps we need to have new signals
“ShuttingDown” and “ShutDown”, then make the
components responsible for this? So, for example,
wifi powers off, server v2 disconnects, logging
stops logging to SD, etc, on “ShuttingDown”. Then SD
unmounts on “ShutDown”.</div>

<div class="">A better solution?</div>

Possibly just by chance and I was lucky
all the reboots before, but I think we

reboot -- see issue #97.<br class="">

FYI: the SD could be restored by a simple
fsck, no data loss. My Linux system also
could mount the SD before the fsck. The
