WLAN/WIFI setup fails if passphrase contains dollar signs $

[dbstf]

What happened

If your WLAN/WIFI password contains dollar sings "$" the WLAN/WIFI setup fails, as the password is saved incorrectly.

What did you expect to happen

Connecting to my WLAN/WIFI SSID after entering the correct password in the Web-UI during initial setup.

How to reproduce

When entering the WLAN/WIFI password in the Web-UI, no connection to the selected SSID can be established.
Manually executing
wpa_passphrase tetSSID 123testpa$sword
yields an incorrect psk hash in wpa_supplicant.conf

network={
        ssid="tetSSID"
        #psk="123testpas"
        psk=fd8a624e2369c1762b6136f80a6e1edc36ddb3ff77c0c688692115aa0e10e210
}

Note that the passphrase incorrectly clips with the dollar sign.
Escaping the dollar sign with a backslash, i.e., \$ fixes this issue. Output of
wpa_passphrase tetSSID 123testpa\$sword
(note the backslash before the dollar sign in the passphrase) yields the correct output:

network={
        ssid="tetSSID"
        #psk="123testpas$word"
        psk=ca491b674c84ea27535fc41601471459dde7541833939b85cf73340df06de5f3
}

I assume the same issue occurs during the initial setup, when the passphrase entered in the Web-UI gets parsed.
This is not a bug in RatOS per-se, but rather due to the "special char nature" of the dollar sign in bash / Linux and arises with every occurring dollar sign.

This was fixed back in january but will require a new image (obviously you can't update before you've connected): Rat-OS/RatOS-configurator#65

It'll be fixed in the next image :)
