So, as long as netconsole can send messages with metadata header, moving the reliability part to userland is trivial. All that's necessary is a program which follows /dev/kmsg, keeps the unacked sequences and implement the same retransmission mechanism. It'd be less reobust in certain failure scenarios and a bit more cumbersome to set up but nothing major and if we do that there'd be no reason to keep the userland part in the kernel tree. If the retransmission and timer parts are bothering, moving those to userland sounds like an acceptable compromise.
