We just opened a box of 50 onion omegas (omega2) and the wifi SSID shows up as "Omega-0001" instead of the usual "Omega-XXXX" where the XXXX is the last four characters on the label.
I am aware that they do this for a few seconds on the first boot or factory reset, but I checked and the 0001 even shows in the terminal/console!
Normally this wouldn't be a problem but we are using these in a workshop with middle and high schoolers, so it is a HUGE problem if every one has the same SSID, because for one, nobody will know which one is theirs and two, neither will their computers.
I found this out after having to manually update the firmware of another 50 omegas so this is disappointing to do. Not sure if it is a bug, but I know updating the firmware will not work.
