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

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.
