[Users] how do you connect to a host's serial console

[Jeremiah Jahn]

That's a nice theory you've got there... :) I'd think a little script
management would go a long way until you have _every_ possible use
case in the system. :)  As a developer I find at some point I always
get talked into adding that extra bit of flexibility even though no
user should ever need it. They always find something I never thought
of.

btw, do I put feature requests in bugzilla, or is there some other place?

Thanks for all of the help.
