Good to know this.
But I think having screen/tmux still has it's value.

For serial console, I don't think screen/tmux can work on that.
(screen can hold serial console as session, but not the other way around)
For tty, it's already have left-alt-F4 console already, there's no
need to having screen/tmux at all.
So I plan to work on network-console only.

If I have done the udeb of screen/tmux, how to build into d-i?
Currently I use "make reallyclean; make
build_kirkwood_network-console" to build d-i image.
But it seems using the udeb from apt repo, not local compiling.
Another question is how to package udeb? I have a few experience on
normal deb packaging, but I have no idea how to do it for udeb.
Any way to install / debug udeb package?
Sorry, there may be too many questions in this email.
Even partly answered reply would be appreciated.
Thank you!
