It defines a variable and its default value in load_rc_config() just after rc.conf is loaded. "rcvar" command shows the current and the default values. This is an attempt to solve a problem that rc.d scripts from third-party software do not have entries in /etc/defaults/rc.conf. The fact that load_rc_config() reads rc.conf only once and /etc/rc invokes the function before running rc.d scripts made developers confused for a long time because load_rc_config() just before run_rc_command() in each rc.d script overrides variables only when the script is directly invoked, not from /etc/rc. Variables defined in set_rcvar are always set in load_rc_config() after loading rc.conf. An rc.d script can now be written in a self-contained manner regarding the related variables as follows: --- name=foo rcvar=foo_enable set_rcvar foo_enable YES "Enable $name" set_rcvar foo_flags "-s" "Flags to $name" ... load_rc_config $name run_rc_command "$@" --- |
