When run as first process on + boot (as PID 1) it may act as init system that brings + up and maintains userspace. + + For compatibility with SysV if systemd is called + as init and a PID that is not + 1 it will execute telinit and pass + all command line arguments unmodified. That means + init and telinit + are mostly equivalent when invoked from normal login sessions. See + telinit8 + for more information. + + + + Options + + The following options are understood: + + + + | + + Prints a short help + text and exits. + + + + + Set default unit to + activate on startup. If not specified + defaults to + default.target. + + + + + Tell systemd to run in + a particular mode. Argument is one of + , + .
