The switch doesn't work yet but "uci get switch-button.@main[0].func"
gets the currently active configured action for button.
I guess that /etc/rc.button/switch is called on every press of the
button.
I have rsynced the whole device before associating with a new device and
after. The only file that got modified was /etc/oui-tertf/client.db.
We intend to have it stored in memory rather than on flash. This should
be okay since the kernel also holds the MAC addresses in memory.
