# Ctrl-alt-delete is handled by/etc/init/control-alt-delete.conf

#

# Terminal Gettys is handled by/etc/init/tty.conf and/etc/init/serial.conf,

# with configuration In/etc/sysconfig/init.

#

# For information on what to write upstart event handlers, or how

# Upstart works, see Init (5), init (8), and Initctl (8).

#

# Default RunLevel. The runlevels used is:

# 0-halt (Do not setinitdefault to this)

# 1-single User mode

# 2-multiuser, without NFS (the same as 3, if you don't have networking)

# 3-full Multiuser mode

# 4-unused

# 5-x11

# 6-reboot (Do not setinitdefault to this)

#
