Hi,
I think, that this problem is related to the way the TLS is handled.
Thus init times out waiting for the ueventd to create all necessary
devices. Init then starts the servicemanager which does no checks on
opening devices.
We have an internal solution but this is not yet ready to be pushed to
the public. However it should work with the prebuilt images.
Br,
Matthias.
