The s6-setsid program

s6-setsid runs a program as session leader.

Interface

     s6-setsid [ -I | -i ] prog...

• s6-setsid creates a new session if it is not a session leader, and becomes session leader of this new session.
• It then executes into prog....

Options

• -i : strict. If s6-setsid is already a session leader, it will exit 111 with an error message.
• -I : loose. If s6-setsid is already a session leader, it will print a warning message, but exec into prog nonetheless. This is the default.
