thanks
Hi Daniel
Thanks for the information. I have forwarded this bug upstream
to see what they think about it.
I suspect that this wait command do not work with the new
init system. With the new init system the services are started
in parallell and due to that it may be so that this --wait command
no longer work due to that it do not know when the default
runlevel has been reached.
But I'll let the upstream team to determine that.
Best regards,
// Ola
