Comment 1 for bug 595715

Hi there, thanks for the report!

As of Ubuntu 10.04, the Byobu now defaults to re-attaching to an open session, rather than launching a new one.

However, it's trivial to launch a new one. Instead, just type:
 $ byobu bash

So running "byobu" will start a new session if none exist, and attach to one if one does exist. And "byobu bash" will start a new session every time.

I'm converting this bug into a question, since it's a really good question :-)

Cheers!
