Upstart examples for logins

You can use names of your choice for the file names of your Upstart job files. The directory where you must place the file depends on your distribution.

• This Upstart job file enables user logins on terminal device hvc1 with mingetty.

  start on runlevel [2345]
  stop on runlevel [01]
  respawn
  exec /sbin/mingetty --noclear hvc1

  With mingetty, you must explicitly export the TERM environment variable to specify the terminal capabilities.

• This Upstart job file enables user logins on terminal device hvc2 with agetty and sets the TERM environment variable to xterm at startup.

  start on runlevel [2345]
  stop on runlevel [01]
  respawn
  exec /sbin/agetty -L 9600 hvc2 xterm

  With agetty, you can specify the value to be set for the TERM environment variable as a parameter.

• This Upstart job file enables user logins on terminal device hvc3 with agetty and sets the TERM environment variable to xterm at startup. The ttyrun program prevents recurrent respawns by stopping with return code 123 if the terminal is not operational.

  start on runlevel [2345]
  stop on runlevel [01]
  respawn
  normal exit 123
  exec /sbin/ttyrun -e 123 hvc3 /sbin/agetty -L 9600 %t xterm

• This Upstart job file enables user logins in single user mode on terminal device hvc0. Instead of /bin/login, the default login program, the /sbin/sulogin login program is used.

  start on runlevel S
  stop on runlevel
  exec /sbin/sulogin hvc0

  Note:

  • The /sbin/sulogin login program requires a login by user root
  • The runlevel specification for single user mode and for emergency mode depends on your distribution.
