NAME
halt - variables that affect the behavior of the shutdown scripts DESCRIPTION
The /etc/default/halt file contains variable settings in POSIX format: VAR=VAL Only one assignment is allowed per line. Comments (starting with '#') are also allowed. OPTIONS
The following variables can be set. HALT If set to poweroff the system will be powered down after it has been brought down. This is the default. If set to halt the system will only be halted after it has been brought down. What exactly this means depends on your hardware. NETDOWN Setting this to no prevents shutdown from shutting down the network intefaces. This is necessary to use Wake-On-Lan. Setting it to yes causes shutdown to also bring down the network interfaces (and thus prevent the machine from being woken up remotely). SEE ALSO
halt(8), shutdown(8). AUTHOR
