[bind10-dev] Handling Disappearing Terminals

[Francis Dupont]

It is a well known issue, cf. nohup (often a shell built-in)
and setsid (the system call, it can be a command too).
BSDs have daemon(3) which does the right thing and was ported to
Linux & co OSs too. But you already know that...

About the analysis IMHO it depends on the flags too: if su calls
the shell as a login shell it will create a new session.
